Actually, I have 2 questions. 1) I’ve always fed my Goldie’s New Life Spectrum pellets. Can I continue to feed this now that they are in a pond or do they need something different? 2). My pleco can’t handle the cold weather months so I ordered a few trapdoor snails to put in the pond. Has anyone had these and do they stay in the pond. Sorry for the newbie questions but appreciate any advice.
