I've currently got a 55g freshwater aquarium that I'm thinking of converting to a saltwater reef setup in a few months, and I've got a couple questions. I've read the pertinent sticky marine threads already, but I'm concerned about fish and invertebrate selection once the tank is ready to go. Basically I'm hoping you'll throw me a few suggestions about types of fish that would do well in a 55g tank, which seems to be relatively small according to what I've read so far. I'm thinking of starting with the generic but safe "clowns and yellow tangs" configuration, but I'd like to include some kind of anemone and perhaps one other type of fish. I was interested in the Picasso Trigger, but it turns out they're aggressive and aren't reef compatible, so no dice. I was also looking into getting a cleaner shrimp. I guess mainly I'm looking for animals that won't outgrow my tank and that won't give me a huge headache while I'm adjusting to the whole saltwater thing. Thoughts?
