Are they bad at this size?These look like gorilla crabs. You don't want them (or at least relegate to the sump).
What size do they become bad, and is it one google it says they are poisonous. Is this true?I think it's more a question that they can grow quickly and become a problem in short order.
They're bad from the outset, and will eat all inverts and even small fish as they grow. Yes, they are poisonous - but this is more with consumption, ie: don't try to cook and eat these crabs.What size do they become bad, and is it one google it says they are poisonous. Is this true?
Crap. I also got a few of these. are they hard to catch? how big do they get, and how big of a fish can they eat?They are the paramount omnivore as far as hitch hikers go. They will gladly eat any fish they can catch, hermits, snails and dont shy away from corals if they are hungry.
They can be hard to trap, but do a few searches for crab trap and you'll find some helpful suggestions. How big? Probably fist size eventually, so whatever they can catch...Crap. I also got a few of these. are they hard to catch? how big do they get, and how big of a fish can they eat?
My smallest fish is two inches how big would it need to be to eat it?They can be hard to trap, but do a few searches for crab trap and you'll find some helpful suggestions. How big? Probably fist size eventually, so whatever they can catch...
So as long as the fish only swims in the water Column and doesn’t lay down it be fine?It’s not always about how close in size the crab is to the fish. It’s about opportunity. The crab can hide all day, and it takes one wrong move from a fish that is small enough to be immobilized by a good pinch. Even these small crabs pack a punch with their claws. if they could pinch you, trust me you would feel it. Ask anyone whos been pinched by a large emerald crab, it’s not the greatest experience trust me. If the crab gets a good pinch in, it will bring the fish close, pinch with the other claw, and then eat it alive. It sounds gruesome, but thats how they do it.
As stated,In short they attack the fish when they sleep and lights r off. Believe me they r a terror. I hv cought 15 till now. U may see some fishes can kill them but none will eat them. Your small fishes will be in a great danger. U can see these crabs hiding in rock holes. If u see your fishes suddenly disappearing, that means crab has eaten your fish. U may also see some 'moults'. Sometimes, U can see them in night with red flashlight.So as long as the fish only swims in the water Column and doesn’t lay down it be fine?

If u see one gorilla crab u may also hv more. U can identify these crabs with their 'sharp' claws. Crabs which feeds on algae, their claws r not sharp, they r kind of flat claws.
It's depend on individual. Aggressive fishes sometimes kill gorilla but you may don't want that kind of fish in your tank. My cinnamon clown used to kill gorilla crabs but it also killed many fishes so best way is to try to remove those crabs.What fish will kill gorilla crabs?
Aren’t gorilla crabs hairy…?These look like gorilla crabs. You don't want them (or at least relegate to the sump).
