Frogspawn Coral


Frogspawn Colony

The Frogspawn coral gets its name from the way the tentacles resemble a clutch of frog eggs.
During the day the tentacles are extended and provide nice movement to the reef which is much
like the movement normally only found in soft corals. On top of the nice movement the tentacles
fluoresce under actinic lighting adding vibrant color to the reef. Frogspawn corals come in a
variety of colors. Some of the most common colors are brown, green, and purple.

Common Names: Frogspawn Coral or Honey Coral

Skill Level: Moderate

Classification: LPS

Disposition:  Aggressive

Light Level:  Moderate

Water Flow: Moderate

Water Conditions: 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.023-1.025

With Frogspawn corals it is especially important to realize that when the lights are off this coral
will extend its sweeper tentacles. These tentacles can reach up to six inches long. Their purpose
is to sting any corals which might be encroaching on its territory. This is why you have to be
careful when placing this coral. The exception is that you can keep frogspawn corals in close
proximity to corals of the same family such as hammer corals.

Frogspawn are a photosynthetic coral and do not need to be directly fed. The coral produces its
food from the lights on your tank. However you can feed your frogspawn coral and it will accept
pieces of meaty foods by catching them in its tentacles. Once or twice a week I will shoot small
pieces of shrimp into the tentacles of my frogspawn. I have noticed a large difference in growth
rate when feeding the coral directly.

It has been my experience that too much flow will make the coral unhappy and the tentacles will
not get full extension. This gives the coral an overall unhealthy look. If the tentacles look as if
they are blowing back inside the skeleton or pushed back so you can see the skeleton through
the tentacles there is probably too much flow. For this reason I would say that moderate water
movement is best. I have my frogspawn coral placed in moderate lighting close to the floor of
my tank.

Coral Placement

Frogspawn propagation of the coral is handled like many other LPS corals. In the picture below you will see where this Frogspawn Coral has coral heads that grow on branches.

Pulling mother colony out of the tank


Coral out of water


Using snips cut the skeleton to separate the heads from the main mother colony where they “fork”.  It’s okay to have your coral out of the water for several minutes.

Proper place to cut the mother colony


Picture of skeleton once it has been cut. This will seal up on its own.


Take the newly cut frogspawn coral and place it back in your tank.


Coral frag about one hour after fragging.


Give your coral several days before you see full polyp extension.
