When I got my fish a year and a half ago he wuz pinkish red with dark red stripes,but iv noticed that now he has red speckles and his fins are looking rather ragged.I have no idea how old he wuz when I bought him so maybe he's getting old ? Or sick ? And another thing, I got a double tank kit and another betta, the tank is a lot smaller than my first bettas tank, will he even care ?
