Yo yo / pakistani loach chasing help?

Question

i have a yo yo loach in my 200l tank and a few days ago i added a slightly larger one and it is torturing it around the tank. i dont have much more room for a few more but i do have another smaller 60l tank wich has room for it. should i just leave it there or should i move it to the smaller one. thanks

Answer 1

Yoyo Loaches are social, and without a large group to establish a real, stable hierarchy, the smallest will be the larger one's whipping boy.  Really, you either need 4-5 or NONE.  As adults (3"+) they are much more tolerant of being kept singly, but when smaller, they rely on groups for protection.  Unless one of them is 3"+, I would recommend taking them all back to the store if you don't have room for a larger group.
