Formalin and Wrasse?

Joluan01 · Mar 17, 2023

Hello!
I have 2 clown fish sick, looks like Brooklynella. In the same tank I have a Blue Hippo tang, Fox Face, Chromis and a yellow wrasse none of these have signs of the disease. Today I received Formalin, my question is, this is safe for all the above fish? Should I treat them all and leave them in a quarantine tank?

Thanks!

What formalin dose are you going to use? 25 ppm is fine for wrasse as long as you provide really good aeration and as long as the wrasse aren’t really sick.
If you don’t treat the whole tank, the Brook may spread to other fish, and at least would be active for a time, keeping you from returning the clowns.

Thank for your response!
I am going to do 1ml of 37% Formalin per gallon saltwater for 45 min x 3 days. After every formalin bath, I'm going to move fish to Qt with copper. Any suggestion?

You said other fish have disease. Can you provide pics under white light for confirmation?
You dont want to treat wrong medication for what you may Not have. For bath- Its 12 drops or .6 mil per gallon. Avoid overdosing.
For QT treatment, you want to use chelated forms such as Coppersafe or copper power and start at 1.75 therapeutic level and increase over 24 hr to 2.0 level and monitor these levels with hanna copper kit - NO Api brand

The other fish looks fine and no sign of disease
