I have a 29g growout that i will be using to house 3 sunnies which will later be put into a 55 or a pond. I can get really nice colored longears at a local creek at around 2 inches and less and I was wondering if I should introduce all the fish at once or if it would be okay to introduce them within the same week. I want to be pretty picky about the fish I choose as some are very colorful and others are not so I am trying to target the perfect fish. Any experiences with aggression levels introducing not at the same time at that size?
