I inherited a betta fish from a cousin of mine, and I've had him for quite some time now. He's always been a very energetic fish, who was always happy to see me, and loved to eat. Now he's recently been very sluggish and tired all the time. Also he barely eats. I know nothing about taking care or betta fish andi have no idea what to do. I've been cleaning his tank every other day because green stuff keeps growing everywhere and I've also gotten rid of his old plants. What do I do?
no I do not know what size tank I have, I also inherited that from my cousin. I'll look to se what size it is when I get home. Anothe thing is he won't eat his food sometimes, I think he hates it, should I try a different brand?
Since they are tropical fish, they need a constant warm temperature. If they are in cold water, they become lethargic, loose color and stop eating. As soon as you get him a heater and his water stays at 76-80*F he'll start acting like himself again.
