hello everyone. i have an eco-system and i have 2 fish that i cant identify in any book. they look close to a monkey shrimp but not quite. deepwater you saw them and i still cannot identfy them. But now i see these little guys all over the place real small and they are in the shapes of shrimps with the antennas and grey bodies. . i think they are baby shrimps but i here that critters grow in sumps. which are they? and what should i do with them>>?
