hey everone i made this pretty sweet setup to house live crabs. i bought the largest critter keeper and put a 10 gallon whisper filter in it. I added a plastic looking tree that they can climb on and hide in, also the tree extends above the water line so they can get out of the water if they need too. the tank is filled with just over a gallon of brackish water that I change every week. I went to richmond beach today and found 5 shore crabs under rocks. 3 of these are HUGE! i would say 4 inches. do you think i should cut off the claws so they dont damage an octo? anyway heres a short video of the tank!
