I have an important question. I recieved a betta fish as a present. He seems to be a very happy fish and plays and swims alot, but he has very little color to him. He has been this way since I recieved him. Is there anything I can do to help this?? One more question. My aunt recently purchased a betta to keep her company, so she bought him a 2 gallon tank, but he hides all the time!! He never comes out and seems to be irratated in his new surroundings!? Any help is greatly appreciated!! Thanks!
