Possibly Ich

[mikev]

This should not be happening with Ick, it tends to be treatable faster.

Possibilities here include
* water is very wrong
* fish is weakened by another disease
--- both really amount to the fish being weaker than it should be
* you managed to acquire (or create) a more resistant strain of ich; possibly you cut off the treatment too early?


What is the water (pH, hardness, amm, nitrite, nitrate, temp), and what is the current treatment procedure?

If the water parameters are fine, you may need to go with higher temp and higher dosing.

Append.

There are diseases out there that are nearly impossible to fight, or the fight stretches into many months --- I'm dealing with such myself now --- but Ick is really not one of them. There should be a reason why it takes you so long, and if you actually did manage to get a resistant strain, salt and temp remain a way of dealing with it. And a UV should help greatly too.

Good luck.
