Not every pleco will get to that size, I'd say it's an average size that doesn't count anomalies that are particularly small or large. Prepare for it to get to that size, though.I also read they get to 10 inches... is that peoples experience?
Plecos are known to be very greedy, and may end up eating smaller fish (like fry), though I've not personally had any experience with this. They're generally very peaceful and passive, and will only become territorial when disturbed by other fish.Good advice thanks!
any advice on tank mates?
