Is okay to put a two one and a half inch albino channel cats in with a 4in rtc hes not agressive one time my brother thru a one molly (super slow one of those fat ones)in there and he left it alone my lil pansy rtc.
RTC's are only pansies while you they are really tiny... like 5" and below... but when you get cocky and figure everything will be alright for a day or two I can get away with this... thats when they flip the script and eat everything in the tank...
