Most likely, but I really like to know everything I have. I am still searching for crabs around the Gulf of Mexico so I can find out what species this is. No luck so far. He does not look like a mithrax to me, the shell looks different. The claws do not look like a gorilla crab, even a juvenile one.Most likely a coral eater
Definitely NOT Pilumnus. Carapace is not trapezoidal enough, and the claws are not large enough proportionally. Claws also don't have the nearly dark black/brown color on the tips. Appearance is more indicative of the Superfamily Majoidea.Its a Pilumnus (hairy crab and Not reef safe. Me- to the toilet. You can place in sump to enjoy, but i'd rather not.
Sump it as i suggested.Definitely NOT Pilumnus. Carapace is not trapezoidal enough, and the claws are not large enough proportionally. Claws also don't have the nearly dark black/brown color on the tips. Appearance is more indicative of the Superfamily Majoidea.
I wouldn't advise killing a crab just because its hairy.
You might as well say you trust basically none of the crabs in the hobby, since even emerald crabs have hairy legs at times. Only true crab common in the hobby that aren't hairy at all are like Acropora crabsI don't trust any hairy crab
It was a lighthearted joke... man people lack the ability to have fun discussions..You might as well say you trust basically none of the crabs in the hobby, since even emerald crabs have hairy legs at times. Only true crab common in the hobby that aren't hairy at all are like Acropora crabs
Sorry, didn't mean to seem like I was attacking you. Please do not take it personally. I just did not want to let someone mistakenly make a decision from that statement, be it a joke or not (which is sometimes hard to tell through just text alone).It was a lighthearted joke... man people lack the ability to have fun discussions..
Sump it as i suggested.
I know some people use mithrax crabs or even other less reef safe crabs to trim their chaeto or caulerpa. Depending on how fast your chaeto grows, it can keep it reasonably trimmed down like a landscaper. That entirely depends on if you ended up with one that has a taste for macroalgae though.It is going to get sumped no matter what, but I love watching things in the sump. Enjoying them also means knowing more about what they are, it is fun to research.
Looks like one that has a high chance of being OK. It looks like a relative of the common emerald mithrax crab. In the gulf of Mexico there are actually several species of Mithraculus crabs (same genus as the emerald crab), and I would wager it is one of them.
It looks most similar to a Mithraculus forceps. Some individuals are simply not as ruby or red as others and variations amongst individuals in a species is quite normal, especially for crabs. Yours looks like a young one. If you disagree, it could be in the Family Majidae or Mithracidae.
Here are two individuals of this species that are not as red as most. Crab 1 Crab 2
How big is the su.p
I think so too, it may be because it is a juvenile or its diet made it so that they aren't as bright.I think we may have a winner, strikingly close. Maybe just different because it is a juvenile? I think this guy came from the Florida Keys. He was probably smaller than a dime when we found him last night.
