I don't see any fish in that tank. I feed my corals fish pooh. Now if you don't have fish, I would suggest some coral foods. Also, what are you doing as far as maintaining alk and calc (and magnesium). Need these guys for corals to grow.
haha i have a convict and purple tang i just had my hands in the tang so they were hiding. i run a calcium reactor so my params are in check, just curious as to what to feed everyone lol and I've heard about the reef energy gunna give the other stuff a try too
Your tank looks amazing. Keep doing what your doing. Sometimes frags need to grow a little bit then they really take off growing. I notice this especially with chalice corals.
I mostly just broadcast feed my fish Reef Frenzy, sometimes mixing in some Rods Food for the smaller particles and sometimes add Oyster Feast.
I've periodically spread Reef Chili throughout the tank but not lately.
So as mentioned above, mostly fish poo. and whatever other food floats by.
