When I was younger I had a large tank with all sorts of tropical fish and took care of them for many years, but when I moved I had to give my tank and all the fish away
. Recently I wanted to start keeping fish again so I researched bettas and my sister and I each got a male betta from the same pet store. Mine is in an 2.77 gallon tank (I know its not big enough but I am going to upgrade soon). My fish seems happy enough, he's active and colorful and is showing no sign of stress or illness but he is being a very picky eater(which I know bettas can be, but I'm worried still). I have been looking around and I know most people say it takes a while for bettas to settle in their new home, but I've had him for a week and there's been no sign of improvement and I'm getting a bit nervous. I'm trying to feed him Aqueon betta food but he's just not taking it.
Also, could someone advise me on how often I should do water changes and how much I should take out, I did one yesterday where I took out about 15% and then replaced it with water. Is it better to add the water treatment directly to the new water before putting it in the tank or put the water in the tank and then put the water treatment in?
Thanks for your help!
