Get them from seahorse source... If you buy WC from ccritters, you need to deworm them in a QT tank for 9 weeks with bring and 3 different meds. For the price of the meds and the water that you will use doing 50% water changes daily, and your time... it makes more sense and usually is less expensive in the long run to buy CB. Dan and Abbie are the best... they are definietly where you want to get your CB dwarfs from.....
