That's where I get a lot of my info. But there's plenty of other places out there that give fishy facts. And if you have any specific questions I'm sure there will be someone here that has hands on experience with the species.
Cardinal Tetras are beautiful. Also the wide variety of Cory Catfish are very cool. German Blue Ram, again stunning. Hmm, I'm going to have trouble picking, good thing I have a long time to go on the tank cycle.
