Fluval Bug Bites Betta Fish Food, Granules for Small to Medium Sized Fish, 1.05 Oz.

You can find the liquid kit here. The nitrate one is a pain. Make sure you shake the heck out of bottle 2 and the tube itself gets shaken a lot. It’s the only one that’s finicky about needing to be shaken thoroughly. For food, Fluval Bug Bites for Bettas and Hikari Betta Bio-Gold are the pellets that have the best nutritional value for bettas. Their stomachs are small so you want to feed them the size of their eye ball (which is the size of their stomach) twice a day. I use Fluval and soak them in tank water first to try and prevent bloating. It’s also good to mix in some live/frozen foods. I do frozen bloodworms, frozen brine shrimp, (these are treats) and mine refused frozen daphnia which sucked since I had to put so much effort into finding it from a local pet store. Frozen mysis shrimp are nutritional enough to be a staple if you end up with a picky brat that refuses pellets, along with the bloodworms and brine shrimp. These packages come in little portion blocks, I have a special sharp knife I use to shave off a sliver of the portion. I wrap the left over up in plastic wrap and then aluminum foil and that keeps it until I’ve used it all. I fold them different ways so I know which one is which. Freeze dried foods aren’t recommended since bettas have a lot of issues with bloating.
