Hello I need some ideas on nano fish to go with Otos and Cherry Shrimp in a 10g long (50cm long). This is going to be an all-moss tank. I have a few ideas: Neon Tetras - Small and not kept for more than a few days before since they always die. Hopefully maybe this time they'll survive. Boraras brigittae - I'd love these but I don't know if I'll ever be able to find them. Galaxy Rasboras - These are a maybe I tend not to like danios much.
