I know it is a Hillstream Loach, but that is a generalization. Can anyone tell me which "Hillstream" it is? I have 2 of them and they are very fun to watch. But I do not know much about them other than they like cooler water and like to play above the aerator wand that i have vertical so it produces more of a stream effect for them. They are about 1 1/2" long and I have had them for 4 months.
