So i noticed today my oscar one of my oscars was acting very stange. I got a closer look, and saw that his fin had been torn up fairly bad, and he had patches of scales missing, and flaking off.

I'm not sure if he's sick, or if he is just fighting with my other one. But It's worrying me a little bit. Anyone know what's going on?

Sorry I don't have a camera, so I can't take pictures.

well in order to help you best we need some information like your water parameters, tank size, tank mates but it sounds to me like possible bullying can't say for sure though

Water is fine. I just had it tested yesterday while I was at my local pet store. They told me it was perfect. I don't remember the results.

I do water changes every other day usually.

My tank, I know is small, 25 Gallon. Not nearly big enough for two oscars. they aren't really that big yet.

I am thinking it is bullying though, I have been watching them since I posted that and the bigger of the two (only by a little bit) seems to be picking on him a bit.

can not help much.... the tank alone is an issue already.
oscar can not thrive healthy in that tank. and you can not
keep good water parameters in that with 2 oscars.

i suggest for happy fish keeping, upgrade.

i back paul 100%
