can anyone tell me why my 2 oscars sit beside one another and vibrate there bodys together.

i always thought it was something they do as a breeding ritual but wouldnt say for sure

Its just of those things oscars do. It can be linked to the breeding ritual but it can also be an agression thing, like establishing a pecking order

they r just uddling up to each other

hey my one do that too, he is all alnoe in the tank (except the pleco) i think it's their way of relaxing! like dogs ha!that's why they r called river dog;)

I had two do it not so long ago day after the bigger of the two had killed the other so aggression there

From what i've seen it appears to be a form of Oscar to Oscar communication for many different reasons. I first saw it amongst two 5" oscars when one of them caught a tough case of Ick from a feeder fish (he was a hog and ate them all before the other O). It was so sick that it would lay on the bottom of the gravel and the other oscar would lay next to it. They would lay head to tail and vibrate the bottom ends of the dorsal fins back and forth. Another time I saw it was with a young 3" oscar who would do that to newcomers to the tank before chasing them or attacking them to remain on top of the pecking order.

My O does that often while I sit near the tank! I don't think it's aggression as he likes my company very much...well, most of the time!!
