I have two bichirs that are showing white spots on their tail that are beginning to gradually grow. There is no fuzz so I’m 99% sure it’s Columnaris. I can’t get a lot of the good fish medications due to a bunch of restrictions, but I have aquarium salt, stuff called fungus clear that has some Nitrofurazone in it, I ordered from Kanaplex but it won’t be here till the 11th, a good bit of methylene blue, and some Doxycycline Hyclate.

so far I’ve left them in a hospital tank with the Doxycycline and methylene Blue they seemed to get better but then as soon as they were back in the big tank they were acting weird again. All they do is sit on the heater.

If it is Columnaris(?)
and the fish showed symptoms in the main tank, putting them in Q T (hospital tank) and then putting them back, in an already infected tank may not be enough.
Once Colomnaris bacteria are in a tank, unless the entir system is treated they are still there (including anything that touched its water.
Nets, siphons, tubing all net to be sanitized..
In fact this gram negative bacteria can go inert, and stay viable in a dry smudge of dirt.
The most effective med is an antibiotic used against gram negative bacteria..

Post pics. Could it be heater burns?! Bichirs don’t usually get columnaris but can. Cover the heater for now.
