Yoyo loach compatibility

hi there.

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.

Loaches really must be in groups of at least 5. They are a remarkably social fish, and observing the continual interaction between members of such a group makes it very evident why this is necessary.

Your concern over problems from the now-dominant loach is wise. But with this species, Botia almorhae, I think you should be OK if you add 4 at the same time. Initial "aggression" will be spread out, and the playful nature will likely take over. I would certainly do this if it were me, without question.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
