I had to rehome a common pleco not too long ago after unwisely purchasing a small 3 inch one, I kept it housed with my froglet ACF in a 20 gallon but then I read up on plecos and how big they get and how they become once they get larger. I do not regret rehoming it, I also have a 55 gallon myself and I felt that was too small for a pleco and I do not plan on getting a 125 gallon tank to accommodate it when full sized.

Honestly ACF should be kept with other ACF there are no suitable tank mates for these guys. The only fish I keep with my ACF are my feeder guppies, which I breed myself.
