tricky thing is if they canabolise ,you wouldn't know about aES deaths ,what makes it even harder to tell it they shed their ectoskeletons wich look like eaten out shrimp shells .Ide like to collect them as they have more interesting colour & behavior(aside from the algae eating bennefits of the AES) but I don't trust them with other shrimp or bottom fish.those tiny pinchers are just too big and menacing for their body size,imo it must be an agressive trait, I'le have my eye on them in the mean time.
