Thats why im separating them then put them together to a larger tank when my other 2 gets big.8 inch monos will probably eat the two inch monos.
Neat observation.I have 4 12-13 inch bass with dithers and two oscars in a 750. O aggression with the bass. Some with the oscars. When they were in a 300 some aggression. When in a 75 the aggression was almost non stop.
