i have a 4in mono pbass and a 4 inch geo my geo has a setup which he dug out and whenever my bass swims past it either my geo or bass try to kill eachother what should i do.
Honestly I think the Geo would kill the bass to be honest but not worth the lost of either Cichlid.
This isn't a mixable mix at there size. I would not risk loosing either one myself. Do you have another tank?
If not you may need to take one or the other to the LFS.
