i have a 5.5g and i ordered 3 nassarius snails, 10 dwarf ceriths, and a ball of chaeto. well, i got the 3 nassarius, and ball of chaeto...but there weren't 10 dwarf ceriths. there were over 40, and he threw in a hermit! this guy is crazy! over on NR there are posts everywhere about him not being able to count lol. he throws in so much more than you ordered that way if anything doesn't make the trip you still have plenty more to fall back on. this guy is so nice and responds very quickly. i recommend him for every order of a cuc. the best part...cost me only $18 total coming from florida. i would have spent 3x that getting this stuff from a local store plus the gas driving there.
