I've had two of my bettas since the beginning of August of this year. They were each in their own 1 gallon tank prior to last weekend when I got a 10 gallon tank and divided it in three. It may just be the better lighting but it really looks like they're brightening up a little.
Also my new betta that I got on Saturday doesn't come to the front much. He usually swims up and down in the back of the tank and will hide in the plants. He seems to be fine and he eats and swims but won't come to the front of the tank too much. Should I be worried or is he still getting used to things?
