I'll admit, I don't have a saltwater tank (not enough space or finances for the time being) but I find marine life to be very fascinating.
I've now seen some very unusual creatures being kept in saltwater aquariums, including sea horses. I'm quite curious about what sorts of marine life can be successfully kept in the home, as I've developed a liking for unusual freshwater fish (such as dragon gobies and african butterfly fish) and would love to someday set up an aquarium for oddball marine creatures.
What are some of the most unusual and/or interesting creatures you've kept in your saltwater aquarium or have worked with before?
