Really aggressive killifish pair!

    Hello everyone. I trialed putting a goby in my new tank (I've rearranged it to make it more like a stream with rocks and stuff), and the killifish pair (even the female) went berserk and tried to kill it! The weird thing is they don't care about the balloon rams in there, but the second I put a new fish in they go crazy. What's the deal here?
    Thanks :)

    Just wanted to add they literally chased it in a pair so Atleast I might get some baby killies :D

    Hmm... EricV breeds them, he can help you.

    Unfortunately I don't have any experience with housing them with gobies and generally keep them in species only tanks for breeding.

    I think they may be getting into breeding mode as they are both ( mainly the male) kind of 'nudging' the rams out of there way if that makes sense. I might have to get rid of them if this problem persists.

    I have seen gardneri get moderately aggressive in community tanks, especially larger males.

    What kind of Goby? If it was a Peacock Gudgeon, the similarity of color pattern might be the trigger.

    No it was a lentipes multirdaiatus female which is basically grey/brown

    Odd. Well, you may never know what it was that got them all riled up over the goby. Guess the only solution is to separate the fish.

    Yeah I guess I might have to get rid of the killis....

    I would suggest that you separate the fish. Could it be that the killifish are becoming territorial as they start to breed?
  12. fishguy122Well Known MemberMember

    That can't be done as I don't have any more tanks that are appropriate for them. I do have a heavily planted 1.6 gallon shrimp bowl but that already has shrimp in it, so I guess they're become dinner of I out one of the killis in it.

    Time for a timeout box. A breeder box with a lid and air filter may be required here.
