My absolute favorite inverts are still my pair of Skunk cleaner shrimps. They have character, and are very vibrant!!!! I like my inverts, because they will just eat straight from your hand. so in the tank I have: 2 skunk cleaner shrimps, a camel or camelback shrimp: very fast, pretty, but can be shy at times, a sponge crab: very laid back, hangs out on top of the sponge as in the pic on my profile, has character, and is the most comfortable eating out of my hand, horseshoe crabs: in the sand most of the time, which is great for stirring up the sand, when they are out, they are entertaining swimmers: a porcelain crab: hides most of the time, seems to be nocturnal, but is amazing at fanning through the water getting debris out, a chocolate chip starfish: for a starfish he is all over the tank! a lot of different hermit crabs, and snails!!!!! And when you have your first outbreak of red algae, and you will, buy some turbo snails. I have Mexicans, that are great, but recently bought Fiji turbo snails and they will polish any algae they come across right off your tank, sand, or rocks!!!! Must haves! I am always on the hunt for more inverts!
