Being new to the hobby i have made one HUGE mistake, i added 3 sally lightfoot crabs to my 120reef. DO NOT ADD THESE TO YOUR REEF TANK!!!! In the last 3 days i found one literally ripping open my baby maxima clam ULTRA and killed it, another one knipping at my larger maxima mantle, not killing it but cutting the mantle. AND, this morning i found my yellow prawn goby that is 4 inches long mauled, not dead (amazing) but ripped up pretty well, hope he makes it. I want them dead!!! My mistake, i admit, now since im ahead of them in the food chain, i want them caught and boiled for crab legs. I have all types of crabs and these sallies are a whole different level of predator. How will i actually successfully catch them? I have a useless eel that doesnt even know he eats crabs, so he is no good. Im really worried about my awesome wrasses that sleep in the rocks, they will be next. If anybody has ever caught a rogue crab/animal please advise. MAN, I GOT THREE IN THERE!! THESE ARE NOT WITH CAUTION/ THEY ARE NOT REEF SAFE IN ANY WAY!!!!
