    Hey guys.
    Three days ago I bought 3 of the Neon Dwarf Rainbow fish to my half way starting plant tank (I guuess 1 female and 2 males aording to the colors).
    Even at the bag I have seen 1 of the males attaking the 2 other's and keep attaking them now and even bulling my angelfish's. What should I do? expend the "school"?
    1 of them keep chasing the 2 other and the angelfish's..

    Normally the solution to the sort of aggression you're seeing in schooling fish is to increase the size of the school. 3 is too small. 6 is the minimum number that people typically mention, although more is better.

    With that said, I can't recommend adding any fish to your tank given the stock you currently have. You're way overcrowded in there. The angelfish aren't suited for the tank, like you mentioned, but neither are the brochis or the whiptail catfish. I would really suggest either getting a bigger tank if that's an option, or rehoming your larger species and focusing on smaller fish more suited to the tank.

    I agree with Brhino, you are a bit overstocked and many fish will soon outgrow your tank, and others will need territory the tank size just won't allow

    I am going to get a whole bunch of rainbowfish in about a month and have been reading up a bit on them. From what I have read 1) Rainbowfish prefer to be in large schools, and 2) they are avid swimmers preferring tanks that are heavily planted on the sides and back with open space in front to dart to and fro.

    It could be they are highly stressed which is what is making them harass each other. It also could be that the fish are slightly too big for the 25 gallon, what I mean is they don't have the room to dart from one end of the tank to the other. The best comparison would be a school of rummy-nose,
    see how they go from one end to another, based on what I have been reading that is what rainbows do too, in groups of at least 8 but preferably 12 or more.

    As advised earlier, too few of a schooling fish causes this type of behavior.

    Neon dwarf rainbows are very active, can be a bit territorial and need a longer tank (36" minimum, 48" is better). They also need a well oxygenated tank and a dGH of 10. A 25 gal, which is 24" wide, is way too small. The rainbows need to be returned or re-homed, They also need a larger school, at least 6, with a M to F ratio of 1:2 (1 male to 2 females). The 2 males could exhaust the female to death in your tank.

    You've done your research! If considering neon dwarf rainbows, be sure to have a well oxygenated tank and a dGH of 10 (very important). Your neon dwarfs will love you for it!
