Odd Duck Posted November 7, 2021 Share Posted November 7, 2021 It’s likely either predation (bites) or fin rot (potentially secondary to bites). I would need a closer picture to tell you more. Link to comment Share on other sites More sharing options...

Colu Posted November 8, 2021 Share Posted November 8, 2021 (edited) Looks like it's had its tail fin bitten off it could be caused by fin rot did you notice the fin gradually deteriorate Edited November 8, 2021 by Colu Link to comment Share on other sites More sharing options...
Samanthabea Posted November 8, 2021 Author Share Posted November 8, 2021 Not that I noticed but it could have been it's a really clean stup though and the red one in the back is about the same size as the other adult(that one's a sward tail) in the tank would it be so clean if they were nipping Link to comment Share on other sites More sharing options...
Odd Duck Posted November 8, 2021 Share Posted November 8, 2021 Agree with @Colu. Looks bitten off with some fin rot in addition to that. Need to have pristine water, add some salt (1 tablespoon per gallon) as long as other fish, snails, and plants will tolerate it. Will likely need some Maracyn to effect any chance of a cure. 1 Link to comment Share on other sites More sharing options...
Samanthabea Posted November 8, 2021 Author Share Posted November 8, 2021 Salts already in the tank the adults weren't doing to good until I made the water slightly brackish I'll have to pick up some meds for him when I go to the store 1 Link to comment Share on other sites More sharing options...
