Ahh, Cleaner Wrasse, Cleaner Wrasse...
One of the first saltwater fish I ever had was a Cleaner Wrasse. It was my favourite fish. It fed very well on frozen foods, flying in the face of the new advice I got. I bought him because in an old book of mine said they were easy to keep. Mine was, it even survived the cycling of the tank ( I didn't know what a "fishless cycle" was back then) . Ironically, cryptocaryon brought him to his untimely demise.
So after the ich breakout had diminished, I got another one. He ate the first night I brought him in, then hid in a cave until he died. Oddly enough, he wasn't stuck; he just liked that cave so much, even to eat was not a good enough reason to leave it, apparently.
