was just wondering how loaches are with shrimp, i have quite a few snails in my planted tank which also contains my amano shrimp so don't want to use chemicals, would a small loach cause any trouble to the shrimp?
Dwarf chain loaches will not bother amano shrimp they are even fine with adult cherry shrimp. They are not the best snail eaters they do eat some, they do need to be in a small group of five at least to be happy though. The killer snail (clea helena) is very effective at snail control, I have to put mts from other tanks in their tank as they ate all the mts, they breed but not fast.
