Injured Tetra

[SpaceFish42]

I just noticed that one of my black neon tetras has a large part of its anal fin missing, and is swimming very oddly. (Corkscrewing, flipping over, swimming upside down, etc.)

I have no idea how it was injured, as I haven't observed any aggression whatsoever from the other fish. What should I do???

 

[SpaceFish42]

Please help! It seems to be getting worse.

What other fish are in the tank?

Other black neons, some bloodfin and lemon tetras, and a small angelfish.

Are you able to isolate the fish that's hurt? My educated guess it that an antibacterial will be needed to keep the wound clean

I just checked on it and the poor little guy died. ? Thanks for the help anyway.

Oh no! I'm sorry. Do you think another fish took a bite out the affected fin?

I didn't notice any other injuries. It could have just been from the stress.

How long did you have the fish in the tank? I think I missed something, why did this fish have stress?

I've had it for several months. I meant that it could have been stressed from the injury.

Oh ok. I'd keep an eye out for aggression just in case it was another fish who caused the injury.
