I would advice against it, goldfish are coldwater and plecos are tropical, and in some cases, the pleco sucks the slime coat of the goldfish, I can suggest a hillstream loach though
Also what could live with a pleco in cold water. Thanks I had a tank for seven months now but something went wrong down the road. I had 8 fish thriving then got a cichlid and things went bad. So sadly I had to flush him down the toilet. And then only one left is the pleco. So yea and after recovering from scars I want fish and I came across this website joined and very helpful joined today.

Woa man, no then never mind, the small species of pleco need at least a 20 gallon, I would get a 29 gallon (30 inches long by 12 inches wide by 18 inches tall) you can comfortably keep 2 in there carefully
