Darren Meyer said:The mixture that we use is rather cheep compaired to most dry mixes . Also the extra yeast for flys , produces tons of flys !!! Have also been told by many top breeders that the fatty acids & vitamins produced by flax seeds is the biggest advantage compaired to other ff media . Just my experince .I'm sure we all use what we find works for the amount of frogs we keep , what is cheepest , and the best first and formost that we can provide for our frogs .
