Does this flagfish have ich? It’s on the back of his dorsal fin.

 

[twentyleagues]

I don't see ich.

 

[Deadeye]

What I’m seeing looks more like it could be lympho or bacterial.

 

[The Masked Shadow]

How could I treat that?

 

[Deadeye]

If it’s lympho, there isn’t really much you can do besides provide clean water and good food (etc.). Lympho is rarely fatal.
If bacterial, treat with an antibiotic like kanaplex or neoplex.
This could be the result of an injury so keep an eye on tankmates.

I removed from tank and he is quarantining. There are Gymnogeophagus Terrapurpurra parents in the tank, and they chase all the fish in their away. Could it be an injury?

 

[Deadeye]

I think it’s possible that it’s an injury. Often that’s where a lot of infections stem from.

 

[The Masked Shadow]

[kno4te]

I don’t see ich.

 

[The Masked Shadow]

So it’s just an injury?
