Corals frag themselves ?

[darkreef]

I'm growing colonies from frags. I find every time I get up to 15-20 heads ... Few heads decide they don't like the colony detach themselves and leave . Scoot few inches over . End result no colonies ... Lots of five headed clusters around my tank .

I shouldn't be complaining really I just went three months without seeing one zoa open to a healthy tank with corals splitting all over the place ..

But kinda worried this is a survival skill from being neglected then all a sudden I spent a month nursing the water quality back to health.

Does this happen to everybody , I'm new to this , tanks been running ten months so its still new .

Just started my 75 gallon build so at least il have lots of corals when it's all set up !
