The Frogspawn Wall Coral, Euphyllia divisa, is often known as the Octopus Coral, Grape Coral, or Honey Coral which needs care, attention, and breeding. It’s a stunning LPS coral with small, bubble-like polyps resembling grapes or a mass of frog eggs. Its coloration ranges from brown to phenomenal inexperienced.

In this article, I am going to talk about Frogspawn Coral Care Guide, Placement, Tips, Wall, Branching.

Frogspawn coral care

The Frogspawn Wall Coral is greatest saved in tanks with reasonable Waterflow, medium lighting, and in the midst of the tank.

The Frogspawn Wall Coral ought to be saved at the very least six inches away from neighboring coral as they prolong their tentacles in the evening and might hurt different corals within the course.

They will additionally profit from supplemental feedings of ready aquarium meals. The Frogspawn Wall Coral is an especially standard LPS coral, and rightfully so, beautiful specimens can actually be the focus of a reef tank.

Frogspawn Coral: Ought to You Add a Frag to Your Tank? Are you interested in retaining the Frogspawn coral in a saltwater aquarium, however, aren’t certain whether it is hard to maintain, the place to place it, or how shortly it’s going to even develop? Let’s dive properly into some tips on Frogspawn coral care, and reply to a few of your questions.

Overview on Frogspawn Coral Care

Through the evenings, its sweeper tentacles can prolong as much as six inches beyond its base into the reef aquarium environment.

It would sting different neighboring corals within the reef aquarium, due to this fact, it’s best to go away loads of room between itself and different kinds of corals.

It’s reasonably troublesome to keep up, however, it’s a standard coral that can thrive below the right situations. It might want to have reasonable to heavy lighting mixed with reasonable water motion inside the aquarium.

For continued good health, it’s going to additionally require the addition of calcium, strontium, and different hint parts to the water.

The symbiotic algae zooxanthellae hosted inside its physique offers the vast majority of its dietary necessities from photosynthesis. It would also profit from further meals within the type of micro-plankton or brine shrimp.

Frogspawn coral care

The important thing to successful Frogspawn coral care in a saltwater aquarium is to supply the coral with aquarium situations that can assist it to thrive. There are three key areas to focus your efforts:

Water chemistry

Correct placement to supply enough water movement and light-weight


Water chemistry wanted for Frogspawn coral care

So as to present sufficient Frogspawn coral care, it’s important to create and preserve steady reef tank water parameters.

Quick facts

Temperature: 78-82 levels Fahrenheit (25.5-27.Eight C)
pH: 8.2
Alkalinity: 8-12
Calcium: 400 ppm
Salinity(measured as particular gravity): 1.025
Ammonia, nitrates, and nitrites = 0

Within the ocean, water currents, waves, and tides deliver oxygen, meals, and vitamins to corals, whereas sweeping away waste.

The solar offers the right light to maintain progress. In a saltwater aquarium, we have now to recreate these situations.

Aquarium pumps and powerheads are used to create life-sustaining water movement and LED lights are usually used to exchange the solar.

The Frogspawn coral isn’t capable of the transfer itself to one of the best locations in your tank, it’s important to decide the placement for it, and the best placement goes to be totally different, from one aquarium to a different.

The key is to suppose like Goldilocks–not the breaking-and-entering half, however the half about not offering an excessive amount of or too little of a good factor.

Water flow

The best Frogspawn coral placement goes to have reasonable water movement–an excessive amount of movement and the coral polyps will retract (and would possibly get broken or tear). Too little movement won’t present sufficient oxygen for sturdy progress.


Proper Frogspawn coral care requires you to supply reasonable light. They are going to bleach below intense lighting and can starve below low ranges of lighting.

A remaining thought on placement

When you’ve got sturdy reef lighting, one of the best placements is often in the direction of the underside of the tank, on or close to the substrate, and off to the aspect or outer perimeter of the aquarium light.

When you’ve got a small nano aquarium with comparatively weak LED lights, chances are you’ll want the coral to be nearer to the center, to obtain sufficient light.

And as talked about before, that very same space ought to have reasonable movement, supplied by a gyre pump or a powerhead.

One other necessary ingredient of the best coral placement is to make sure sufficient house between your Frogspawn coral and different corals in the aquarium.

Sweeping stings

Sweeper tentacles are a problem with the Frogspawn coral. It’s a comparatively aggressive coral and the sweeper tentacles pack a sting and can injury close by corals.

Sweeper tentacles can get together with this species, so it’s best to offer the frogspawn coral a large berth–like 6 inches on each aspect–to be secure.

Should you cheat and attempt to stack different corals too near the Frogspawn coral, you’ll remorse it, as a result of the coral will merely burn its method into the aquascape.

The one exception to this rule is with different comparable Euphyllia species, just like the anchor and torch corals, which should not be broken by the sweeper tentacle of a neighboring colony.

So when you can in any respect handle it, attempt to put different comparable species close by. Right here’s a tip I picked up in Borneman’s book, Aquarium Corals:

To maintain the formation of sweeper tentacles down, keep away from inserting these corals in a spot with exceptionally quick water movement.


This genus for probably the most half has been propagated extensively in captivity and is a superb candidate for aquaculture.

The branching varieties are typically a lot better candidates in comparison with the wall varieties. It’s affordable to believe {that a} sustainable harvest might be achieved in time.

There may be nevertheless a lot much less common technique of propagation that frogspawn is able to: Polyp Bailout. Polyp bailout is a stress response to unfavorable tank situations that sure stony corals can activate as a final ditch effort to save lots of themselves.

Throughout polyp bailout, stony corals are killing off their very own connective tissue by way of apoptosis.

For those which might be unfamiliar with the time period, apoptosis is programmed cell demise versus necrosis which is a traumatic cell demise.

Apoptosis is an extremely regulated and managed course of so the coral polyps bailing out because of stress are doing so in direct calculated response to an exogenous menace. 


Acclimation goes to be key. Even when you’ve got the right place on your new coral. It may not be good instantly. If there’s a considerably kind of intense lighting or dramatic kind of water movement, the change would possibly stress your coral.

An excessive amount of stress and the coral may bleach and die, or simply die. So it’s usually greatest to cut back your aquarium lights and steadily improve the depth to assist your coral in higher acclimate to the conditions in your saltwater aquarium.

Frogspawn Coral Care


The Frogspawn coral, like all corals, is an animal–and animals must eat. That may be complicated, generally, when interested by corals, as a result of we purchase costly aquarium lights, to supply a vitality supply for them.

However the corals aren’t vegetation, they’re animals, that ‘home’ tiny organisms known as zooxanthellae.

These zooxanthellae are the creatures that harness the sunshine energy to make sugars–and so they do present a good quantity of the vitamin for the coral, however, it’s nonetheless usually greatest so that you can feed your frogspawn, along with offering it with sufficient light.

The approach used usually known as ‘spot feeding’. That’s the place you’re taking a tool just like the Sea Squirt or Julian’s Thing and drop some small, meaty meals on the polyps.

The important thing or the ‘trick’ right here is to match the meal particle measurement with what the coral needs to eat, which takes some trial and error sometimes.

There are additionally hobbyists who report success feeding tiny pellets, though I’ve not personally had success with this.

Are Frogspawn corals hard to maintain?

Frogspawn corals are hardy and engaging LPS species which might be relatively simple to take care of, by coral requirements, if the right aquarium situations are provided for.

Types of Frogspawn coral

There are two totally different species of Frogspawn coral that might be considered generally saved within the saltwater aquarium interest. The commonest species has the scientific title Euphyllia paradivisa.

Euphyllia is the genus that accommodates Hammer corals and Torch corals, and the opposite species of Frogspawn coral, named Euphyllia divisia.

E. paradivisa grows as clusters of small, skinny branches (like a coral bouquet) and E. divisa grows as a single-walled coral.

E. paradivisa is simpler to frag and due to this fact frags are more generally available and due to this fact I’d consider it more standard.

You will see that that sure native fish shops or online shops can also categorize them by their shade: blue or inexperienced, for example.

The more exotic the color morph, the dearer the coral is, usually talking, though coloration can be influenced by the lighting spectrum used.

Frogspawn Coral Care guide

As mentioned earlier, the Frogspawn coral is a hardy LPS species. They don’t are inclined to have numerous problems within the dwelling aquarium. The largest points to organize for in Frogspawn coral care :

Aggression between coral species
Polyps being nipped by a not-so-reef-safe saltwater fish
Polyps not opening-up
Bodily injury because of dealing with
Brown jelly infections

Aggression between coral species

Life as a coral should be robust. They’re at the mercy of their surroundings and environment. However, that doesn’t imply they’re pushovers.

Corals have tailored very refined methods to guard themselves against rivals of their environments.

Some corals and algae launch chemical compounds, others try to grow over and shade out, and lots of, together with the Frogspawn coral, attempt to sting their neighbors into submission.

Should you see the injury on the border polyps between totally different species, you’ll have a problem with aggression.

The most effective guess, generally, is to trim again, or frag the corals, and/or relocate the colony or frags, to create more space.

Often, aquarium homeowners have a kind of ‘often reef secure’ fish species, that do nip at coral polyps sufficient to disturb the Frogspawn coral.

If the nipping is aggressive sufficient, the coral frag could not prolong its polyps, and hassle may result from that. The treatment right here is to establish the issue and isolate the offending fish.

If Euphyllia divisa polyps aren’t expanded, it’s actually an indication that one thing is improper. Test to ensure nothing is bodily disturbing your coral (like a clownfish that wishes the coral to be an anemone or a butterflyfish or angelfish with a polyp-nipping behavior.

Please additionally examine the water movement and water parameters. Keep in mind the Goldilocks precept with respect to water movement and make sure the reef aquarium water parameters are steady.

If the polyps are retracted, this can be a bellwether of lower than splendid water situations. Test these final entries in your reef journal and search for altering water parameters.

Generally, performing an easy water change might help get the water situations again on observation.

Bodily injury because of dealing with

The massive, fleshy polyps of LPS corals just like the Frogspawn are susceptible to break.

You should be extremely cautious when dealing with them, transferring them, adjusting dwell rock close by–and watch out to make sure that water movement is suitable, or the polyps would possibly tear.

Brown jelly infections

The Frogspawn coral is vulnerable to brown jelly infections. A brown jelly infection tends to be the result of two components: bodily injury to the coral, adopted by the opportunistic infection with a protozoan or different illness agent that causes the speedy lack of polyps, and infrequently, your complete colony.


Corals that might be severely harassed by some environmental queue, like maybe being put too immediately below the white-hot aquarium lights, could bear bleaching–which is the place the coral expels the photosynthetic symbiotic zooxanthellae.

Relying on how severe the bleaching and stress are, the coral can generally be nursed again, or chances are you’ll lose your complete Frogspawn coral colony.

Brown jelly infections

Brown jelly infections are a major problem that may be encountered when retaining the Frogspawn coral.

Usually, the very first thing that occurs is a few kinds of trauma or injury to the coral polyps themselves.

The injured coral is then considered subjected to a protozoan an infection–and people protozoans flip the polyps right into a gross-smelling, disgusting-looking brown jelly.

Brown jelly infections spread shortly throughout the entire coral, typically killing your complete colony. I’m not a veterinarian, however, the recommendation I’ve seen when treating this situation is alongside the traces of ‘amputation’.

It is advisable to take away the colony from the water after which lower away or frag any contaminated areas and a number of the bordering healthy space, permitting the coral to get well in isolation, to make sure the infection doesn’t spread.

Frogspawn Coral branch Care

The branching number of frogspawn coral, Euphyllia paradivisa, is fragged pretty simply by snapping, reducing, or sawing the branches close to the bottom and utilizing cyanoacrylate glue to affix the frag to your most well-liked piece of dwell rock.


Found in shallow reef environments shielded from wave motion. Members of the category Anthozoa are both gonochoric or hermaphroditic.

Mature gametes are shed into the coelenteron and spawned by way of the mouth. Life cycle: The zygote develops right into a planktonic planula larva.

Metamorphosis begins with the early morphogenesis of tentacles, septa, and pharynx before larval settlement on the aboral end.
