Well most of the time fish get crack from the crystal meth pebbles that come mixed in with other pebbles. The first fish to find the crack sells it among the school of fish in the tank. If this is a problem in your tank, it may be beneficial to buy another fish and pay him in blood worms to figure out which fish is selling the crack. Please contact me if you have any more questions.
