My ORA Extreme Misbar Clowns like from one day to the next have developed black spots everywhere....Is this common? Or could there be something wrong with them? Do they have a disease that I need to treat immediately? Both have black freckles all over. I have had them for a couple of months. They have always been solid orange until a couple of days ago they just appeared. Both at the same time! One clown is larger than the other and has always been. Please let me know what you think. Thanks!
