fishbase is easy to search
you can search by common name or even part of common name
just change the dropdown box that says contains to begins with, ends with or is. so if you are looking for a fish that has pike in its common name
you can search fo
pik (contains), [b]pi[/i] (begins with), [b]ke[/i] (ends with) or pike (is)
some searches will result in large lists being generated
the best way to search is by genus, putting boita in the genus search and changing the dropdown box to
contains will generate a list of every fish that contains botia in the genus, including chromobotia, gobiobotia etc
more specialist searches can be done too, say you wish to find all fish found in lake victoria, use the search area called Information by Ecosystem
click the drop down box and find lake victoria, then check the box marked all fish.
once you've played around on it, you have hours of 'fun' finding stuff out about your fav fish
