My first betta fish I had lived in a tiny tank and lived for a couple years (the longest out of all my bettas) and I was really young when I had all my bettas so I didn't know any better than to make them live in little tanks and feed them flakes that the petstore told me to buy.
Almost a week ago I bought my first betta in a couple of years and I wasn't really prepared to bring him home (kinda a rescue betta) and so I put him in a tiny kritter keeper until I could buy him something bigger.. He didn't even move, he wouldn't swim around or anything (it wasn't decorated). After doing a lot of research on this site and many others I finally understand what bettas need and for my birthday (a month from today) I am getting a 5gal glass tank with a hood light and filter and heater.
Until then I have him in a 1/2 gallon Marina betta kit. (Bigger than the kritter keeper) and I have a small plastic plant with NO sharp edges and some gravel. I change the water everyday to make sure it's not harmful to him. He has been swimming around like crazy! He doesn't stop! He goes in and out of his little plant and hides in it from time to time and he made a huge bubble nest (almost half an inch high). Does that mean his is content? I really want him to be as happy as possible until I get his 5gal tank.
Also I have a question about food.. I know they are suppose to have a variety so I have betta flakes, dried blood worms and pellets.. He spits both the pellets and flakes out and won't eat them... he will only eat the worms.. Why?
