I once baught a crab at Petco. It died a month later. I went there today and humidity and temp were bad. Anyway i saw this cute cute crab a white grey color and another crab a white, brown, and black striped color. So should i get them? I mean there was legs littering the ground and it was really bad, will that crab die like the other crab will it harm my crabs at home? Will it be sick? I have not had good expieriences there! Will the crbs be OK? Petco so far for me does not take good care of crabs!
