I currently have a royal, gold nugget, vampire and common pleoc in a 125 gallon tank how many other plecos could i put in the tank. i was looking to get a mango pleco still and hopefully another any suggest what the other pleco i get would be.
EDIT I don't think you should add more plecos, you have 4 plecos which all grow huge and in your 125 gallon tank, the 4 plecs would have just over 30 gallons of space each which isn't fair on the fish.
