Thanks for the link. It's currently under construction, but I put it in my favorites and will keep checking back.
When I went to work today for feeders, I noticed that one of the puffers had a hunk taken out of it's rear end!! One of the others must have really chomped it, because that's all that was in that tank. I brought him home to see if I could heal him up, but I don't think he is going to make it. I feel horrible for him. Right behind is butt, looks like someone sliced him with a really sharp knife almost to his backbone. He acts fine, but is soooo thin!!

OHHHHHH, I just looked, and he ate a piece of crab bite food!! That's good. I just gave him some more, and he's eating. Yayyyy!! I am giving melafix. Any other ideas??
Thanks again,
Zyla
