The Puffer Forum

Ok so this morning when i woke up, one of my puffers was sick. he wasn't hardly moving. When he did move, it was pretty much just slamming himself into the rocks. His color was dark, he was fat looking, his eyes were flush with his face, instead of protruded and glancing about. Also, I noticed these little bumps that started to stick out on his sides. He settled on the bottom, quit moving, and eventually died within just a few hours. I want to know if u guys think my other one is at risk... he looks fine... I haven't touched or changed anything with the tank, and he was fine last night.

*edit* the puffers are young GSPs

Definately check the water parameters. Do you have another empty tank?
