Can I add a cat?

  • We are currently upgrading MFK. thanks! -neo
Your only problem is your pleaco for that reason i would get an active cat like a pair of 4 lined pims. Judging from your tank pic you will need to add a place for them to hide

The pleco is gonna go in the sump refugium. So if I add some hiding spots the Raphael should be ok?
 
Featherfin sypo would be your good bet.
