This is the situation hopeing to turn it into a solution on here. I currently have a 90cube which houses a red scooter blenny and I'm thinkin about addin a pellet eatin ora mandarin into my system I have plenty of copedos for them to eat. But, the problem is will they coexist with each other? I have been told that one would kill the other and rather than seeing that happen I'd like to see if anyone on here has had success with this tag team. Any advice or experience would be appreciated
