i was in petco the other day and they had a common pleco in a floating bag and it was about 5-6 inches long it was pretty big and i know they dont sell ones that big so i asked the guy is that for sale and he said its up for adoption someone just brought it in so i said ill take it ive had it for about 2 weeks or more now and its doing great i have it in a 55 gallon tank it was full of algae on the glass and now it has cleaned all the glass it hides in this cave all day and i feed my discus fish in this tank sinking 1mm pellets and it comes out and it will eat those i also drop a algae wafer in there at night so its eating good but i was wondering is this healthy for it should i start feeding it vegatables too like cucumber or should i just keep letting it eat pellets and wafers thanks for the help also i do have drift wood in there for it
