Interestingly enough, I've found that browsing eBay, of all places, is a great place to find some of the best Betta pictures. It actually makes sense. Thank about it. People are trying to sell their product ( in this case a Betta) so they take gorgeous pictures in attempt to catch buyers. Not to mention there are new sales posted all the time. So the pictures are always 'updated'. Now how cool is that?!
Of course you may also end up finding something you wish to purchase too! eBay indeed has some very cool and some very strange things for sale.
