bought him and he was fine at the store. took him home floated him 15 mins slowly added my water tot he bag about 1/4 cup every 10 mins after the inital 15 minute float netted hima nd let him go. he immediatly tried to hide. i have a tree ornament with a cave in it, but he would go from the top of the water constatnly trying to hide on or around my poerheads at one point the weirdo was letting his tail end kind of suck to the filter intake and hung out. i left for 20 min or so come back and he's on the substrate breathing a thousand miles a minute. next thing i know he's floating about sideways upside down, i check my wter which was 0 nitrite 30 nitrate and 7.5 ph and 0 ammonia. go and come back 20 mins again and he's having convulsions and dies. everyone else is fine just like they were. i'm stumped.
