I got a spotted mandarin from the lfs today for my 20L because it was eating frozen brine there. So I brougt it home, dumped it into the tank, and fed the tank. I decided to try som bloodworms for my shrimps, and the mandarin decided to eat a worm. He spat it out 3 times, and on the 4th, finally swallowed it. I was shocked. Totally forgot to grab the camera. Next time I'll get pics!
