Cleanup crew for a 40 gal?

[inigomontoya]

Currently, I have three Astrea (sp) snails in my 40 gallon tank. My Spec Grav is at 1.023 and I want to get more LR and a decent cleanup crew. I had two red legged hermits that killed each other and I will never purchase those again!! My LFS seems to just put all cleanup crew while they are very small into the same tank and couldn't identify them when I asked what they were.. Any recommendations of anyones preference would be great! Oh, I also have a 96 watt on its way if that makes a difference on what I can get? Thanks!

well if your lfs cant identify their own critters you shouldnt buy from them your best bet would to buy a cleanup crew off of saltwaterfish.com i've got 20 of each blue leg hermits red leg and hawaiian zebra i think the zebras are the best while the blue legs are the most aggressive they like to eat snails the reds are ok also if you have a sand bed get the cerinth snails they dig through it also the nassarius is a good snail
