Then 1fish2fish suggested double mesh dividers..so I added another divider and now the fish can't see eachother..just in case I put Clampy (who has turned into a tailbiter but loves the current from the filter and Pantheon in..Pantheon is a ct who isn't a tailbiter..so far)
It really works! They can't see eachother so far..
*Please note that the divider that is hidden behind the strip of electrical tape is proper-it is the diy kind with the plastic binder spines and aquarium sealant which I made from the thread here, the visible divider is just stuck in as it is to solve the visibility issue-don't just stick a divider like that to keep fish apart!:)*
