Possible bully in the tank.
I thought I was dealing with an illness and treated. In the aftermath it seems one of my male rainbows (possibly the Bosemani) is bullying the other male.
As of now all the fish are fine except my Australian male. His fins are bad and the Bosemani has some knicks on his scales. Yesterday they were showing off and circling but I didn't see anything serious.
Things I changed recently? Added 3 Cories and changed up all the plants (maybe not enough hiding?).
More recently lost a female Australian.
Think of pulling them out, rearranging and adding more hiding spots. I have read about adding fish but am hesitant in case there is a problem with the tank.
Will add pics soon.
