I have been setting up a tank where I can keep fish that aren't compatible with a my reeftank, such as a lionfish. First fish in the tank after cycling were small perch and 'stripeys' that I caught myself. All, about 1 cm length. Also some small glass shrimp. I figured they'd eventually end up as lionfish food when I finally bought one.
Oh boy was I right. I got home this morning with a young lionfish (about 6 or 7 cm). As I was acclimating him, he was attacking the inquisitive perch and stripeys through the bag !! When I released him, he immediately went into stalk mode, and within 5 minutes, had his first catch, a shrimp. Within 20 minutes he stalked and caught 3 fish. He is now sitting with a full stomach, looking quite pleased with himself.
