I looked around online but actually had trouble finding an answer for once!
Do you know if zebra otos and otos of a different species (unknown, but think they are vestitus or vittatus...i am real bad at figuring out what I have) will shoal together? I have 4 of the type I have now, and could possibly add a couple/3 of the zebras but wondering if I actually need 4 or more of each species as I have read Otos prefer to shoal.
