Cool cat. I have one that is about 4 in. long &* is housed w/ a tiretrack eel & a fantail goldfish lol. They all get along great & the eel & catfish eat chopped earthworms, brine, & blood worms w/ gusto. Bumble bee's will decimate feeder guppies too. I love the color/pattern on them, too bad they don't get bigger.
