Regarding corals, this is where the tank becomes a different kind of reef tank. The two predominant corals is
branching fire coral and
fragile saucer coral.
Now gulf corals are illegal to collect or otherwise hold in the hobby. The exception is what is included on the aqua-cultured rock. However it does not appear that either coral is common on the aqua-cultured rock. I will still have some homework to do here on what facsimiles I can use for these two corals.
One contender is
Pavona sp Green Cactus Coral.
Finding a good source for a yellow branching fire coral might be harder than the other.
What is notably absent from this reef is any of the soft corals, such as polys and gorgonias.
