hi i have a 3" red devil in a 5 gallon tank and I have a 6" JD, 4" green terror, a female convict about 3", and a 7" pleco inn a 37 gallon tank. i'm getting either a 75 or 90 gallon tank in a few days. i'm just wondering if they will still reach full size they are all less than 10 months old and i got the red devil about a month ago. my convict doesnt seem to grow anymore at all its pretty small is that normal? i just dont want to stunt their growth
