i have two oscars one rd tiger and one red oscar . the red tiger is 8in and red osacr is 6. i am going to get a red devil in it when it is 5in or 6. do u think this is to crowded for a 30gl?

2 oscars and 1 red devil is way to much for a 30gallon. the red devil is alot more aggresive and may kill them. i would get at least a 125 gallon. but bigger the better .
