What's wrong with these zoos?

[PuffersKick]

I bought these about a month ago and they were full, big, and beautiful. Now a month later they look like this.



Some of them still open. but nothing like before. And I've got several colonnies of zoos, and this is the only one doing this. Looks like some white sponge or something covering them.

What's going on with them? Are the salvageable?

Do you see any predators? Sometimes colonies will close up for a few eeks and just re-open when they want.

Try fragging what you can and move them to a different part of the tank or even a different tank if you have one.

I cant tell from the picture but are there any white spots? if so I would suggest a furan2 dip.... also some people have been having luck with vitamin C dosing.... check out teh zoo forum for more info on both
