I’ll be using RO/DI water for this tank, as I can’t keep anything that’s not insanely hard-water happy in my water. I plan to keep my snails happy by adding minerals, but I’m still trying to figure out how to do that without killing everyone else. It’s going to be very heavily planted, and since bettas have bad vision, I doubt he’ll even notice the shrimp. Slightly worried about my other fish, but I’m not planning to keep anything else very territorial. Maybe the BN pleco would eat them, but probably not. Think the snail is probably the best idea, though. Real cute, unproblematic, and they have the funniest antics.
