Another newer color that has created a stir in the Betta world. A heavy thick build up thick of silvery/white metallic layers of that almost resembles armor are called Dragons. We are also starting to see this Dragon look in a blue color. Fish should have full metallic mask. A good Dragon will be completely and evenly covered with the Dragon scales. Lighter areas or areas missing the heavy metallic covering all together are a fault in this color. These fish often are shown in a bicolor class, so good contrast between body and fin colors will make them competitive. If the coloring completely covers the fins they could be shown in the metallic class.

I have seen this same color change in my betta “Grumpy”. I was wondering if changing surroundings can affect or trigger the change? We moved grumpy from a two and a half gallon bowl, to a ten gallon tank for himself. Now he is in a 29 gallon with 4 other fish. In a matter of weeks he went from predominantly white to blue. I noticed in the picture it appears as though the betta is now in a tank with other fish as well.

A great indicator of illness in bettas is a change in color. Fungal or bacterial infections often leave patches of fuzzy-looking or discolored spots along the body of a fish. A complete water change along with routine fungal treatment should eliminate infection. Ich is another common disease; it appears as white spots along the body and fins. Ich can be fatal if left untreated, but an increase in water temperature combined with ich medication will clear up any lasting infection. Velvet also causes a change in color and can be fatal if left untreated. Velvet coats the gills and scales in a slimy yellow or brown film. Treat velvet with aquarium salt and a water treatment product, and do so as soon as you detect symptoms to save your fish.
