Copperband is not feeling well

[Colossus67]

Hello everyone,

So I added some new fish to my new tank last week. By doing so, this started a mini cucle and got an ammonia spike up to 0.6ppm but mow under 0.1. I added Prime to try and reduce stress as much as possible the fishes. My Copperband has a small blck mass on his side fin as shown on pictured and 2 and 3 of them on the back fin as well. Any idea on what it is? He is eating frozen food so thats good...

All the other fishes are fine

Thanks for your help!

Does any one have a clue?

It could be a mild case or an early stage of Lymphocystis if this is primarily on the edges of the fins.
Judging by the small round white spots in its clear parts of the fins it also seems that the fish has a light Cryptocaryon infection.

It would help to know the history of the fish and what your quarantine protocol is.

Thank you for your prompt reply. The fish was introduced in my new tank last week. So he is fairly new. No quarantine was done from the LFS to my place. I do have a spare tank that I started 2 days ago on case I have to treat with meds. It is small thiugh, a 10 gallon cube tank. My tank started a mini cycle when I introduce the fishes last week with an amonia spike that surely didn’t help. He ests well though Mysis and Brine shrimps

Does the LFS use copper in their fish system? Lymphocystis often shows up after copper treatment or after the fish was stressed over a prolonged period of time, which is usually the case with newly captured fish. Both, copper and stress, compromise the immune system and therefore promote infections.
Lymphocystis is a virus infection and in most cases not lethal. Like a cold it will go away after a while on its own if the fish in kept in a stress free and healthy environment.
