  1. Question Neon Tetra-Large Bump?

    0 Not allowed!
    Hello, I have a Neon Tetra with what looks like a huge blister. It has had gotten a large black dot on its side a while back, its spine is now curved but it seems healthy and happy otherwise (its color has been as brilliant as all the others). Recently (in the past couple of days) the black dot formed into a rather large whitish blister looking thing. Below are some images of the blister, but unfortunate I don't have any of the original affliction of the black dot.

    Some specs my tank. 20 gallon with 11 tetras and many live plants. I do weekly water changes of 1/3 to 1/2 of the water. I have not introduced any new fish in months, long before the black dot appeared.

    If anybody might know what this is I would be grateful if they could let me know. thanks for your time.

    Looks like some kind of fungus, and some fin rot. I would get some fungal meds and treat the entire tank. API makes some, as well as Jungle. Wal Mart carries Jungle I believe. Follow the directions, and hopefully it will clear up.

    You need to get him out of there and away from your other fish before he infects them all with something unknown. Especially with the mention of his spine being curved. His tail is rotting away, as well, and he looks unwell. Just put him down. Never keep ill fish with your well fish.

    Agreed with LH. It's a sure bet he's going to kick it soon. That tail looks like it's going to fall off. Same thing happened to my Black Phantom Tetras, so it could be bad breeding which led to incurable mutations and secondary diseases. Or maybe Neon Tetra Disease. =/ Either way, it's probably uncomfortable and you don't want to risk infecting the other inhabitants.
