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 !

What types of corals are doing this?

[darkreef]

My zoas I think I figured it out . Only my high up ones are doing this so I think my lights are to strong and there detaching and moving down . You would think the whole colony would move not just five or six though ?

[Coral Hoarder]

zoas and plays dont move persay as for whats hapening i duno any metals in the watter ??? are they melting or detaching do you have the ones detached in your tank ?

Oh they move ,always to where you don't want like the edge of the frag tile . Sometimes they just need there own space and once the start to grow they will fill in the space between faster than if they didn't move.

That's good there showing good color and open even at night . Spreading fast .
