I just finished setting up my new 55 Gallon tank. I am going to be putting my bristlenose pleco, 1 common pleco, Royal Pleco, Rubber-lip pleco, cory and syno in it. What else should I add? Some more Cories? maybe some "normal" catfish. I was thinking I would do all pleco/catfish. Or do you think my oscar would be ok in there with what I have now. It has a sand bottom. I'll post some pictures tomorrow.
