hey guys I'm new to having rbp. the 4 i do have are about 3-5 inch's . i went out and bought 25 more there just dimes right now. there in a 250 gallon. my question is . think it is safe for them to be in the same tank with out a divider? a couple got in the big guys tank they didn't really chase it but if the little one gets to close they definitely stare it down and chase a lil. i cant tell if its playing or eating time lol. so i guess I'm asking if i took the divider down will they live together with out losing them all
