Hello! My grandfather has a 5 year old lone Yoyo/Pakistani Loach (~3") in a 25gal tank. I was doing research to spruce up the tank and maybe add a few colorful fish/larger shrimp. Any stocking advice on tank mates for the loach? I'd really like a shrimp (bamboo/sulawesi) or mystery snail to help him keep the tank clean as well- anyone know if they'd make good tank mates? Any advice would be helpful- thank you!
