I have a maroon clown in a 55 gallon. Can I add any other clowns in there? Also can two blennies coexist in that size tank? If so, what would you recommend ?
As long as its another maroon clown you should be ok if you want them to pair make sure that the new one is smaller than the one you have now sense the one you currently have is probably already female. You would probably be ok adding one blenny, two in a tank that size would probably become a issue as they settle in.
