Ok, I just found out my pleco is a common. I thought he was a BN but I was wrong. He is in a 90 gallon tank with 2 blue gouramis, 4 rosy barbs(planning on keeping 1-3 of my rosy barb babies in another tank), 2 cherry barbs, 1 dojo loach, 5 platies, and 11 zebra danios. I really like the way my pleco looks but I know that when he is full grown he will produce alot of waste and I want to get another dojo loach too. If I took him back what are some smaller algae eaters that I could get? If I keep him can I still add a couple rosy barbs and another dojo? For filtration I have a Fluval 304 and an AQ 500. Thanks
