sick green puffer
He was in a 29g tank with his 3 puffer buddies, 2 leaf cichlids, a handful of feeder minnows (for our oscar tank), and 2 recently added knifefish. He was already acting a little sluggish when we added the knifefish saturday, and I noticed the red rings on his belly while waching to make sure the new additions got along ok. Tank temp stays in the 78-80 degree range, all other water conditions were good...ammonia .25, nitrites 0, ph about 7.2 I think. This tank was set up & cycled a couple of weeks ago, after we moved oscars to a larger tank. At this point, I'd really like to know if I'm prolonging his suffering, or if he has something he can recover from with time, love, & care. We've grown rather attached to him, but he just looks so sad & miserable (maybe just lonely in the hospital tank? He's very sociable!). We'd appreciate any insight. My hubbie says he doesn't look as red this am, but he's still just sitting on the bottom of the tank. Thanks for responding!
