hey guys, was sitting down for a movie with the missus tonight when i noticed after a while my two oscars where fighting. REALLY going at each other, alot more than normal. the smaller one has ended up with a chunk out near the right gill, cuts up the side and bite marks all over its face.
not sure what to do about this, he is picking on her but im not sure if it is flirting?

any help would be great. cheers!

dont worry baout the wound, as long as yr water conditions r good it'll heal fast, how big r yr oscars? as if u have 2 males, when maturing, they reach a point where they will not tolirate another male in their vasinity... or do u def know they r male and female? how big is yr tank?

one is roughly 7.5 inch, the other 9 inch. not sure of their sexes.tank is a 6ft 600 liter, fairly big...

i said "he" and "her" but it is just our nicks for them

Keep an eye on this aggression, at that size it is possible they are reaching sexual maturity, and as Matt stated, 2 males wont work in the same tank..

So if it continues you may have to separate.

does the injury looks like this (white spot at gill plate was due to muscle detached)

not quite that big paul, but there is a little bit of flesh hanging off.

As long as your water is good the wound will heal quickly. Keep an eye out for further injuries and if it gets real bad (one fish hiding all the time or always having injuries) then you will have to seperate.
