no PLECOS, they produce so much waste, no joke, your water will probably look like a swamp in 4 days because of it. im sorry to say this, and youll need a stronger filter (20gal filter) and a siphon to clean its poop up every week. black moors, orandas, ryukins, fantails, calico fantails. calico fantails are best. they are simple easy-to-maintain fish. and about the pleco, they grow to be a foot and will eventually eat your coldwater fish so watch out. get a calico fantail. they are so cute and simple! remember that you must do water changes once a week with a SIPHON. it will take up 35% of your water. refill water, add some water conditioner and your all set! Bless your fish and i hope its free of disease when you get it! take care of it!
