I’m fairly certain these are amphipods but they are really big. Some are about 1”. They are hard to get a picture of but I’ve circled one here with a frag plug and an emerald crab for scale. I’d say this one when he was moving was about a half inch but I’ve seen some about twice the size. The color seems to be and alternating dark grey and light grey banding.
my question is should I have any concerns about them? I’ve generally understood amphipods to not be a nuisance other than eating some copepods but I’m concerned that they are so large they won’t have a natural predator in the tank.
