I recently pickup up 2 emerald crabs to help keep the algae on my LR
groomed. And go figure, they are too good at it. They're mowing down too much algae now. I've even supplemented with Dried Algae strips but they still clean the rock too well. Any tips for catching one of these boogers to relocate him to another tank? Once the net hits the water they pull into a crevice in the LR
and disappear. Was wondering if anyone had an idea for a trap so I can "catch the crabs".
