Blind Crab


New member
I have a mithrax crab and hes normally really scared of people getting close to the tank or lights turning on. I took a picture of the tank at night using flash and I think he may have gotten blinded by the flash. This morning when the lights came on, he was just sitting on top of a rock as if he couldnt tell. (normally he scurries away as soon as there is light) Could he be BLIND?! Will that affect his algae eating capabilities?

Test him. Try to poke him and see if he responds.

FWIW most crabs find their food by taste, smell and touch rather than sight.
