Cons: None for myself
These little guys are such a wonderful addition to my own tank, not only for their bold colors, but they are great fun to watch popping in and out between all of the crevases and openings in the live rock as well. Super easy to care for and are very hardy to boot! My tank is a 75 gal. reef tank which also houses corals, mushrooms, anemones, green chromis, a yellow tang, clown fish, sea urchins, an arrow crab, and a variety of snails as well. I would recommend them to anyone wanting added movement and color.
