From what I have red Breeding is very difficult and rare in captivity. As such its hard to come across info on it.

I would have thought it is more likley that one of the fish is going white due to stress of being hased all the time, not because shes pregnant.



What tank have you get these in. I cant seem to see them in your profile

I've seen this before. It's not breeding behavior...atleast I saw no eggs and no fry and they kept doing it. Once they get older it gets more and more aggressive until the smaller shark simply hides all the time. Mine didn't even come out for food. I eventually had to get rid of them because they were killing each other. I had 3 in a 55.

They do turn pale when under a lot of stress. The pale one is not happy at all.

I'm not even sure if there's a documented case of rbs breeding in captivity. Not saying they can't be but it's not very likely.

It sounds more like one is trying to establish dominance over the other. Are they kind of close in size? If so, the other one that's swimming away might know he's not tougher but is unwilling to give in when cornered. Piranhas close in size do the same thing.

I would only keep 1 rbs in a tank unless it was 125g or more. They hate each other and will harass until death. They also don't get along well with barbs and tetras who are fin nippers, generally speaking.
