Maybe it was 4 inches when your friend put it into the pond last spring. Fish grow really fast in outdoor ponds, or at least that has been my experience. Hope you don't have a lot of live plants in your tank. Going to need a lot of algae wafers.
so that pleco just came out of the pond now? how low of a temp can common/sailfins handle?
i know fancier varietys are strickly tropical but i hear the above two are able to handle low 60's...can they go lower?
Sure, its 11 inches now, but when it gets cold, it shrinks up to about 4...
