Yes I am aware that the mountain minnow is a cold water fish but was not aware when I brought him and I think I would rather have him in there until he dies rather than going back to the fish shop where it would be sold as a tropical fish again anyway. My temperature is 26 celcuis so not boiling but not cold water either. I'm not sure what breed the pleco is but have put a pic of him in the pleco section for someone to identify but nothing yet . I think it could be a bristle nose but not sure and would you stock anything else or leave it at that number as I do want some Cory's from tom
