How long was he in there hiding before looking bad and going belly up?
I used 5tsp of conditioner per instructions on the bottle.
he hid behind the airline for like 20 mins....long enough for me to smoke two cigarettes and get really anxious. Then he moved out of there and started swimming sideways for a few mins then started going belly up. Thats when i yanked him back into the old tank. He acted funny for about 5 mins after that then was right back to his normal behavior. I did notice something floating in the net that looked like some of his food after I put him in the new tank like he had thrown it up. However, I didn't think this to be noteworthy before because if somebody stuck a net in my living room and scopped me up and tossed me somewhere new, I'd probably puke too.
the tank had been previously used as a reptile tank by my friend so I cleaned it the same way I clean any new tank: bleach, rinsed it out, cleaned it out again with water then flushed it with warm water before putting in the new rocks and such. the pH is a little high (around 8 ) but he should be used to that because the tank he's in now sits at about the same pH because of his waste.
