Looking for some advice.  I have a small torch coral collection in a 20 gallon cube.  They all seem to be thriving and my blue tip torch has grown multiple heads over the last year.  However, I can’t seem to get the long tentacle extension I see with other indo torches.  Any suggestions?  Maybe lighting or flow?
light=Ai prime 16hd
Alk=7.3
