i picked up a baby rtc at a lfs by me. its tiny. 2.5inches or so was very active.i put him in a established tank by himself last night, was fine, came out this morning and he was out of it. swimming weird.seemed lacking energy and has his mouth open almost gulping but his mouth stays open. i tested the water its all pristine, temp at 78, and no ammonia or nitrites at all nitrates are 5ppm. and ph is 6.8 hes alonre in a 40breeder until hes bigger enough to go in the rubbermaid pond with the others. any ideas? he ate a rosie last night also
