If you love Bettas like we do, you will feed them Xtreme's floating Betta pellets. Although Bettas thrive on all kinds of foods, you want to enhance the real natural colours of each fish. Most colouring foods change the colour or highlight one over another; not natural. Here's why Xtreme is different. The developer and owner of Florida Exotic Fish Sales needed a food that would make all the fish on his farm, over 500,000 plus, look just like they do in the wild. He wanted to make sure the colours were brilliant. But, not all of his customers use Xtreme, so he wanted to make sure that some other food that might be used in the fish store would not change the natural colour of the fish. So, these are the best ingredients, perfectly formulated to bring out the colours of the fish found in nature. Oh, BTW - We include a cool .5cc portion spoon in each 2.5 oz jar so you don't over feed. Use Betta Pellets sparingly but use with confidence. And, if you loved the 1.5 formula, you and your Bettas are going to flip over the new 1 mm floating formula.
