Whilst at the subject, maybe having basic water parameter ranges (Temp, pH, GH) as well would be a good idea. Another idea would be to have "Compaitibility/Suitable tankmates" and "Furniture [tank decorations]" fields as well.
Take a look at the Cat-eLog at Planet catfish for how that works. http://www.planetcatfish.com/catelog
However, I would also like to say to Dave S. that the problem with people buying fish that grow too large is usually beginner fish-keepers that either haven't got a clue that fish will outgrow their surroundings. I agree that it's handy to have a single place to look for the size information, but I think solving the "Buying a fish that outgrows their tank" is a case of educating the fish-keeper in the first instance, which very much depends on the shop's attitude. In a shop where the customer just says "I'll have one of them", and it happens to be an Oscar, and the shop-staff without asking any further questions just bags the fish and says "That'll be 6 dollars", the beginner fish-keeper will just end up with a fish that is too big for his/her tank... A good shop is going to ask about the tank-size, tank-mates, etc, before selling the fish [and it's not just the size of the tank that matters, of course - A 200 gallon tank may well be a good one for a pair of Oscars, but if the tank is full of small fish, it's not suitable to keep Oscars there...].
