Here we have our Hillstream Loaches. They grow to be about 2-3 inches. It is best to either get one or three so they do not bully the weaker one over food or territory. These are peaceful fish towards other community species. They do well in planted aquariums and like plenty of places to hide when they want to. Hillstream Loaches feed on algae, insect larvae, daphnia, and frozen or live brine shrimp.
