I am stocking a 29gal and want to add snails but i have a few questions first.My stocking plan is going to be something like this i hope:10 guppies, snails, some ghost shrimp, and some type of loachs. I am wanting to add stingray loaches since they only get 3in big, but im not sure if they will eat the snails? If they dont, then how many yoyo loaches should i add, because i like them too. Sorry for so many questions,oops one more.Will they eat the shrimp?
