So I have a RBTA hes doing great.. and I also have a Rainbow BTA..I put him in a strainer with my clowns to hope he would host and turned the lights down 50% for about 24 hours..he is now bleaching and I removed him as soon as I noticed it..and thee clowns (buggers still won't host!). I placed him back to his original spot and he moved under the rocks like he was hiding from the light.. he is opening during the day a bit but gets basically 0 light and I moved him out from under the rocks and the next week hes back hiding again in the rockwork. I thought I'd leave him there for a little while.. I tried to feed him but he is normally closed up and never FULLY open like my other RBTA my water is perfect alk is 9 cal is 450 mag is 1400 nirate 0 phos 0 any advice?
