Diamond's fins are clamped so bad that his tail looks like it's twisted. 
He's in a 10 gallon which is divided in three sections for three of my bettas. They can see each other, but they don't really pay attention to each other, and I made sure to give them hiding places. He has a nice little cave to swim through/hide in, a plant, and the tank heater in his side, which still leaves him plenty of room to swim around. The tank is filtered, and I put a little salt and colloidal silver in the water every time I do a change. His fins have been clamped like this for a couple weeks now... at first I thought it was because he had a slight case of fin rot, but that is almost completely gone, and he's still doing it. He still eats okay, builds bubble nests, flares at his reflection... but his fins are always clamped when he's not flaring. What could be causing it?
