I forgot to mention earlier that when removing a porcelain crab from a tank full of maxi minis be careful your hand doesn't get to close! Needless to say it's been about a week and I still have a rash on my hand! Oddly enough when I put the maxi minis in that I bought from RC and when I removed the maxi minis from my 230g tank to put in this tank I never got stung.
The day after I got stung (iphone pic but you can see how red my knuckles are)
Today (not as red but still a bumpy rash that is itchy and irritated)
