I have a tank, 300g housing a few plecos, a rtc pangassius catfish and a oscar I got last week hes about 8". I put a new albino oscar in there last night... about 5" my rts has swalloed it!! I dont get it ther is loads of other fish aka a 7" bala that would od been much easier to swallow and assorted different things but he ate the big albino... I dont get it..... he has a very fat belly this morning lol....
