What is wrong with my Electric Blue Acara

  • We are currently upgrading MFK. thanks! -neo
I’ll just echo what others have said and that keeping it isolated and in clean water is the best you can do. Kanaplex would be good in the case of infection, the fins worsening on their own could be a sign. IME kanaplex is good for that.
If it were columnaris (which I am very confident that it’s not), not many antibiotics work on it. I’ve had some success with seachem polyguard (if it were columnaris to begin with).
 
Please keep us updated. There are many open- ended threads like this that can be found with searching, that contain no outcome/resolution.... leading to continued uncertainty.

These are the type threads that can really help the next guy who is looking for assistance as to what steps to possibly take to help their own fish.
 
Columnaris is pretty aggressive, and has been known to wipe out a fish (and a tank) in very short order. I really don't think it's that.

The new fin damage looks like injury as well. Could there be something in the quarantine tank that he couldve got hurt on if getting spooked? Fin rot is usally much more consistent throughout, and can look like the edges are melting so-to-speak, with fraying and sometimes a white hue.

With fin damage from other fish, I have had pretty good results with 2 products: Melafix (believe it or not), and Kordon's Fish Protector. With that said, I think the clean water and salt is still the best medicine.

As for eating, my EBA absolutely cannot resist an earthworm. Have you seen if he reacts to a live wiggler? That is an option. You can also soak some bloodworms in garlic guard and Maracyn 2, to cover the antibiotic base. I wouldn't treat the water column, given the Kanaplex didn't work.
Thank you for the time to write all that out. I’ll try what you’re suggesting and hopefully he will eat some worms. I’ll update as soon as anything changes. Thank you all for helping
