  1. Default Bully Black Skirt Tetra


    0 Not allowed!
    Every now and again my Black Skirts will sort of swoop around and chase each other for split seconds, not nipping just chasing, however ive noticed one of them is worse than the others. He has taken residence at the centre of my tank and chases the others away if they come too close. I have White Cloud Minnows in the tank which arent being bothered at all, just the other Tetras. I only have 4 at the moment, will adding more stop this from happening? One of them has had his top fin ripped up a bit by the bully so something needs to happen.

    Adding more should help. This sounds like a textbook case of what happens when you keep schoolers in too small of a group, especially since black skirt tetras, while not the most vicious schoolers, are nippier than most. If you have the space and the filtration capacity I'd aim for a dozen of them.

    Yeah 10-12 depending on your tank would help curtail bad behavior.

    +1 to both of the above

    The last time I kept black shirt tetras, they were very nippy, and even a little aggressive at times until I increased the school size from 5 to 10. These guys really do need a larger school size
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Well to be honest I wasnt planning on having that many, I was thinking of having 7 or 8 tops as they grow quite large and I only have a 27 gallon (31" in length).

    I was planning to add 3 more once my tank has finished cycling, as I also want to have other species in my tank such as a Betta, amano shrimp, filter shrimp, dwarf frogs, and an Apistogramma Agassizii (according to aqadvisor I can do these species with 7 Black Skirts and still be under my tank capacity).

    Btw I know a Betta + Black Skirts is commonly considered a risky move but ive seen a lot of examples of them being kept together with zero problems so im going to try it once my school has been built up. From what ive seen on youtube a school of Black Skirts keep to themselves rather than bother other fish in the tank, even my 4 dont bother the Minnows at all.

    OK - so why are you looking to "risk it"? It's not just the black skirts you would need to be concerned about - some bettas can be nasty with other fish as well.

    Not all fish are recommended to be housed together whether or not others have done it successfully. Just my 2 cents.

    I have 6 and they seem to be just fine. I have not introduced any other fish yet, so I don't have any experience to share about the current number and behavior when I do. My 6 are varying sizes too, I'll say 2 lg, 2 md 2 sl. They chase each other, even the smallest I've caught chasing around the largest. No signs of nipping though.

    IMO it is very much trial and error in this hobby. Majority would say about Blackskirt Tetras best kept in group of 10+ and their know for nipping, but I've read posts where users don't experience this behavior in smaller groups either.

    You need time to watch your fish, and if you see aggression take the new fish back. Most places are willing. It's not like the fish see you on the other side of the glass and go "hey we better behave as he's watching us". You should see the aggression pretty earlier on and have adequate time to take them back to store before to much stress or worse occurs to either fish. IMO

    Never had nippy ones either but I've always have large schools. You just need a few more.

    Because I really like them and want one, if I end up getting an overly aggressive one i'll take it back and get another, my local store always has dozens in stock.

    Im definitely upping my Black Skirt school to at least 7, might consider a few more depending on how they behave towards each other + the Betta.

    In a tank your size seven should be fine.
