I recently lost a yoyo loach that I had had for a long time. I still have his/her companion. I want to get a few more so he/she will have company but I worry about size differences. The one I have now is big, and the ones I do get will most certainly be smaller. Should I worry about aggression?
He seems to be ok as he is.. He frolics with the other bottom dwellers in my tank, ie all the cories, but I am not opposed to getting some more yoyos, I just worry about them not getting along well due to differences in size.
