pleco - how big?

[Briarmoor]

well, they do make pond heaters...

Thanks, Pica. I'll check with my sister-in-law and see if her pond is heated. I have friends at work with a pond and will ask them too. Think a pleco in a pond with plenty to eat would bother goldfish slime coat? My mom had one that did that, but her others haven't bothered them.
