I have got 2 pairs of Kribs breeding in my tank, one after the other. I have got other fish like Swordtails, Neons and Guppies in there.
Now, both pairs seemed to have got the spawning thing right, as they both have successfully laid eggs and hatched them. I have been keeping an eye out for one pair which had their fry for about 3 weeks beforehand.
Now, one day, the fry has all disappeared. I assume their parents must have chased them away as they are quite big now (about 1cm each). However, due to the other fish in the tank, I knew those fry won't be long lived.
So when do I separate them from their parents? And what would be the best way? A hose?
