Black skirt tetra with torn fins

  1. celizabethh3 Member Member

    I have a small school of skirt tetras (four black and two white) in my 36 gallon and I've noticed that one of them has half of its dorsal fin ripped off and its anal fin is torn in places. I know they're quite nippy and usually most of them have small tears that heal quickly but this guy is looking pretty beat up. The damage happened sometime between last night and this morning. (S)he still eats and swims normally, just missing some of the fin.

    Should I treat the tank with anything as an extra precaution? I'm aware of Pimafix and Melafix and could order some online if they're not available at my LFS. I also have a bottle of ParaGuard and GarlicGuard arriving tomorrow. I do weekly water changes of about 20% and condition with Prime. Water parameters are 0, 0 and between 5 - 10. The temperature is kept between 75 and 78 (fluctuates on warmer days.) Along with the tetras, I have platys, danios, a male dwarf gourami and a gold CAE. I know that the CAE will need to be rehomed in the future and I'm 100% sure that he's not the one causing the damage, the DG isn't either. The tetras are always chasing and attacking each other.

    I can get pictures tomorrow if anyone needs to see them. But in the meantime, do I wait it out and hope the fins heal by themselves or is there something I should do to help out? Thanks!

    You shouldn't have to medicate. Just keep the water conditions as perfect as possible and the fish will heal.
    You definitely have to figure out which fish caused it or else the little guy will only get worse.

    I test my water parameters frequently and as soon as I see anything wrong, I do a water change. I know one of those products, I believe Melafix? can aid in the healing process but I have never personally used it.

    I know for sure it's another one of the black skirts, possibly the largest of them all. I expected them to be nippy but not to the point where fins are missing. Surprisingly, they keep it amongst themselves. I can't help but wonder if he's being picked on because he's shaped differently compared to the other skirts. Do fish bully other fish because they're "different?" I'll keep an eye on everyone though and see if I can find the one who is causing the damage and I'll rehome them if need be. Thanks! :)
