Who's Got Snails

[Puff]

i was told that halloween hermit crabs are extremely aggressive. is that the case? or are they no more aggressive than scarlet or blue legged hermits? they look friggin COOL!!!

my nassirus snails are on the rocks quite often, but im not sure how much work they do. my astreas on the other hand are constantly on the rocks and glass cleaning away. one of my fighting conchs also cleans the rocks quite often.
