We bought a used 125g tank the other day. It was used as a saltwater tank and contained a Lion Fish and a Stars and Stripes puffer. We took the tank home and cleaned it out, inside and out. After we got it done my fiancce and I each have sore spots on our hands, almost like we were stung by something. Even though we never came in direct contact with the lion fish, could we have picked up the ends of his spnes while cleaning the tank?
