How to catch a Gorilla Crab in a reef tank
If you want to remove a Gorilla Crab from your aquarium without killing it, you can set up a trap to catch it. Rather than chasing it around your tank with a pair of tweezers, you can buy a pest trap or crab trap online or at a pet store.
If you would rather trap the crab yourself, you can use a shot glass to catch it. A shot glass will only work if the Gorilla Crab is still small. If the Gorilla Crab is too big to be caught in a shot glass, you can use a bigger glass. For bait, you can use a piece of raw shrimp or raw bay scallop.
Once you have your glass and your bait, put the glass at the bottom of the tank so it is resting at an angle against a rock. The idea is to place it so that the crab can crawl into it. Put the bait into the bottom of the glass.
A shot glass makes a good crab trap because the crab will not be able to climb out of it, since the inside of the shot glass is smooth.
Keep an eye out for signs of other Gorilla Crabs in your tank. Just because you caught one doesn’t mean you caught them all.
