I have a pair of 6" Piranha in a 55G tank with a pair of Silver Dollars. Recently the twp RBP's have been occasionally rubbing against the decor. No new fish or plants have ever been introduced into this tank, and the only live food is earthworms daily.

Ammonia+ 0; Nitrites 0.5ppm, Nitrates 30ppm. As far as I can see there are no visible spots or other lesions on any of the fish. I have raised the temp to 30 C and added a little aquarium salt. In case this doesnt work and if I need to medicate the tank I want to know if someone has had experience in safely using Formalin+malachite green and other medications such as Fluke- Tabs on Piranha.

i do not think there is anything worng. they just might feel like rubbing themselves. had never used those medince that much. Melafix and Pimafix will take care of most problems, and they work great, on most things.

I wouldn't be to worried as long as they don't display any signs of disease and only occasionally rubb against the decor.
