My spotted and striped Raphael cats are my favorite fish. Here is a link to info on them at Planet Catfish:
http://www.planetcatfish.com/core/index.htm - click on Cat ELog, then look them up by scientific name (Platydoras costatus) or by Common Name.
The spotted is very shy, and never comes out when the lights are on. The striped will come out on occasion to get food, but not often anymore. I always have way too many snails -pond, MTS, and ramshorns. The morning after I first put the striped Raphael in the aquarium, I thought there were a significant number of snail missing. Sure, enough, later that evening when I saw him again, it looked like he had swallowed a bouncy ball! He has since slowed down on eating so many, and their population has recovered.
