A. borrelli right pectoral fin change color!

[mer2623]

As subject stated above, the right pectoral fins of my borrelli male turns into black. Is this a kind of disease?

Thanks

As long as he's still using the fin normally, its probably OK. If the fin starts looking paralyzed or showing reduced mobility, that's not good - maybe a tumor or infection in the muscle or nerves that control the fin.

A photo will help.

Tough decision. If you have access to other males I'd say yes, separate him, but if they're hard to get where you are and you're hoping to get some fry from this pair before he dies, then you might choose to leave them together. Is he still eating well and does his breathing look normal? If so he might still be OK for breeding; if breathing looks hard or appetite is weak, then he's probably too far gone and you should get him away from other fish that don't show any symptoms.

Decide to release the pair in my 3ft tank with other fish. He still looks ok as he is competing for food.

It doesn't look like a disease problem to me. It looks more like nerve damage that won't permit the chromatophores from expanding/changing colors. Other than not looking perfect, it shouldn't cause your fish undue problems.

Mike - did you miss post #4 in which he said the fish has lost its left fin? If so i think this is more than just a chromatophore nerve control issue. But if he's still eating well, there's hope.

Hi Gerald, you're right its the left fin that he lost..sorry my thread title is wrong. Im still observing him now and still looks ok. Are there any chance that the fin will grows back?

If it was bitten off I'd say yes it could grow back, but if an infection or tumor destroyed it, then I doubt it. How does the fin stump look? Open sore or healed over? Are there still stubs of fin rays, or is lost all the way down to the fleshy base of the fin?

The fin stump is close and no more fin rays.

 

[Mike Wise]

If there are not fin rays present, it is unlikely that the pectoral will grow back. I wonder if the nerve damage possibly isn't related to the fin loss, or if it caused blood flow to the pectoral fin to stop??? Still, if the fish is eating and behaving normally, it should be OK and still be used as a breeder.

I think as Mike, the problem could be a color problem, not a very bad thing.
