I have a 20 gallon and I want to add 3 green blue chromis in it will they kill each other? And I want to add different fish later on. Will it be ok or will they just kill all the other fish that I add later.

Do you think I should get 5? And later on would I be able to add 2 clownfish?. Is that okay for a 20gallon if I’m doing weekly water changes and have very good filtration ?Welcome to Reef2Reef!
I prefer to keep green chromis in groups of five or more to try and spread any aggression out among all of them. With just 3, you may find that one gets picked on too much.
Another issue is that it is difficult to find good quality green chromis, so many of them come in with Uronema infections or are really thin. Personally, I’ve stopped buying the small ones due to the high mortality rate.

Best in group of 5-7-9 and so forth. Smaller numbers are often weeded out by an aggressor. They are Not difficult to acclimate- Its a matter of upon purchase observing their bodies for imperfections, seeing them eat and see how they interact with each other in a store displayI have a 20 gallon and I want to add 3 green blue chromis in it will they kill each other?
