Cohabitating raphael catfish

I have a 125 gallon tank with a large featherfin catfish and a male venustus cichlid in it the cichlid is like 4" long and the featherfin is like 6", i want to put my raphael catfish in there , hes 3 to 4 inches, also debating my common Trinidad pleco going in there hes smaller , like 3 inches maybe 4 and a lil skinny , i am only versed in a few types of cichlids behavior , will the raphael and the pleco hold their own or will they end up an expensive chew toy?

 

Thanks thats what i was hoping to hear
