Fin Rot???

Miketc17 · Sep 22, 2020

Got a pair of these Friday and the one eats like a pig and this one hasn't eaten since I got them. It looks like fin rot to me. Opinions? Treatment plan?

Ammonia 0
Nitrite 0
Nitrate 10

Definitely severe erosion on the caudal fin. Were the two fish paired up when you got them? The other one isn’t bullying this one is it?
Any treatment Is going to require treatment with an antibiotic, can you move it to a QT? Do you have any meds on hand?

Yes they were paired up when I got them. There is zero bullying from any other fish. I monitor my fish closely lol. I plan on setting up a hospital tank tomorrow. What meds do I need? So you do think it’s fin rot?

Yes, this pretty much has to be a bacterial infection. Trouble is, if it started just out of the blue, and not a result of getting injured, it is going to prove to be pretty virulent. You need a broad spectrum, gram negative antibiotic...Maracyn II is usually pretty easy to find in stores. Seachem has some better products if your LFS carries them.

I bought seachem kanaplex. The second dose is due this evening. Do I do a water change before I dose the kanaplex?

As long as the water quality is fine, you don't need to change any prior to the treatment. I would monitor ammonia and pH during the treatment. Three doses, 48 hours apart like the label says. I should add that in Noga's book, he recommends a 50% water change between treatments - can't argue with that, always safer to change than not to!
