So I came across this website while doing some research for a blackwater biotope that I might setup soon. I was extremely impressed with how well this site is laid out and how much information is packed into it. It basically tells you all of the known species of fish living in a particular river (given a list of nearly every major river, worldwide). The site breaks down information really well and very scientifically. As you can probably assume, I am very impressed. I hope you guys can enjoy it and I hope that it helps you all out as much as it helped me. http://fish.mongabay.com/data/ecosystem_index.htm
