another question for the fish guys

I have a decent sized Pleco in my 60 now and would probably get a pair for a 125 if I get one. I know cichlids can’t be mixed with any other kind of fish due to their aggressive nature, but I really like the coloration on some of them. Either way seting up the tank wouldn’t happen for a few months so I would have plenty of time to plan out what fish would inhabit it. Either way if the stand is the dimensions I want it would be a good deal for a hardwood stand and I could sell the tank seperately to recover some of the money.
