i have a 29g DT too. i have a blue leg hermits, nassarius snails, torchus snails, 1 turbo snail, and 1 emrald. After my tank had settled down i found it to be too much for my tank. I need to overfeed meaty food to help sustain the crabs and nassarius snails. i also have to throw in some nori here and there to help feed the other snails. if i were to do it all again i think i'd go with more nassarius snails, the torchus snails, and maybe some Cerith snails. i'd also keep the crab but not so much as part of the CUC. I just think she's cool. The reason i wouldnt get blue legs again is because they ate some of my nassarius snail for shells (i had plenty of empty shells around the tank) and they bother my zoas/pallys pretty often. The turbos are cool too, but they are so large that they knock over my frags that arent glued down and slow eat a lot. what ever you choose, take it slow. get a little now, wait a bit and if u need more add a little bit more. if you dont, you'll need to care for their needs down the line. best to just get the appropriate amount and let them live in a sustainable number.
