Going back a couple of years, we had lots of clean up crew. Tone then decided it was a MUST to get a Valentino (I believe a dwarf puffer like fish). I have to say he was very handsome and extremely amusing to watch. We took him back to our LFS last week because as gorgeous as he was, as much as we loved watching him and as graceful as he was.....we really missed our clean-up crew. Our Valentino was one spoilt boy. In the two years we had him he managed to munch his way through all our clean-up crew including a couple of huge red spotted shrimp, cleaning shrimps and all but a handful of snails. Consequently the tank suffered too - probably the reason why our bubble tip nem had soooooo many babies. Anyway, Valentino has now been re-homed. We took 23 nems to the LFS, took out half the rock, have now re-furbished the sand and are in the process of re-stocking the clean up crew. Last week we put in half a dozen nassurius (spelling?) snails, half a dozen snails that have quite a long cone shaped shell. Two of those snails that have very shiny shells and delve into the sand and bought a silver-bellied wrasse and a jade wrasse. (We were overrun with the casings of those tiny worms that live in the sand - most of which we scooped out before putting in the new sand). We will continue to increase the number of snails.......I understand one clean-up crew for each litre of water? We did find a small black cucumber wrapped around one of the rocks and we have a spider? Well we call it a spider. It lives under the rocks, it's middle is about the size of a 10p piece and it has 5 or 6 legs? Anyway, we would like to get some crabs.......I don't like the red and blue legged ones as the last batch we had kept killing the snails to get their shells. SO, my question is "what crabs would you recommend" and also "what other clean-up crew"? thanks in advance!!!!
