I currently have a small clown loach in a 29 gallon with my dwarf gourami and bristle nose pleco. Have a huge snail problem so he’s in there to get a handle on the snails. I know that eventually he will outgrow the tank, so I plan on transferring him to my 150 at that time. That tank is stocked with shubunkins. My lfs told me that the loaches love to suck on the goldfish slime coat. Has anyone ever seen this behavior? Is it something I should be concerned about? Should this prohibit putting them together in the first place?
