HELP I guess the BTA died and my tank is not doing well :

[arash53]

Oh something bad happened to my tank this morning and I think it is something to do with BTA!
5 of my fishes died at a same time!

I think maybe the BTA died and toxic my tank , is that possible ?

I did a 50% water change and my scooter and bio color bleny back to normal now.

Still something is wrong all my britle stars tons are out they are all over my tank even on my corals!

What should I do?

Ouch, that's harsh. That sounds like it died and caused a crash.

The small brittles are probably feasting on all the decayed matter in the water. Have you checked all your parameters?
