My goldfish is chasing my other goldfish.

I have two feeder goldfish in my tank for about 5 months now with my two oscars. Apparently, the oscars don't both the goldfish what so ever, even when the goldfish's head constantly nudges the oscars mouth the oscar does nothing whatsoever. Anyways, I have grown acustomed to keeping the goldfish, however, for some reason one of the goldfish is chasing the other goldfish none stop and it is ramming his head into the other goldfishes bottom and side to the point where I think its going to seriously harm the other goldfish. I know that they are too young to breed, but why are they doing this?

 

Thats what my male guppy does to the female :wink:

 

That definitely sounds like breeding behavior to me. How big are they? How long have you had them?

I personally think that they are wayyyyy to young. I have had them for about 5 months now and the two of them are about 3/3.5 inches.

 

I have fantails & shubunkins that are 3" and 4" respectively and they're breeding. But they're smaller varieties than commons. And I just did some looking around and found a site that said they can start breeding anywhere from 9 months to 2 years. So assuming yours where 4 months when you got them (which sounds reasonable), I'd say it's possible that they are breeding.

BTW, do any of them have little white bumps on their gill plates?

Wow! That would be great. As for the white bumps I haven't really checked.

 

wow 9 months-2 years is so long :shock:
