I am new to betta owning and these forums. So interesting story, I work at guest services at a local mall in my area (with no pet store on location). A housekeeping worker came up to the booth with a betta in a stater bros. bag with very little water. She said she didn't want to flush him, so she brought him here. I then took him and got some room temp water and a large dairy queen cup to put him in. So borrowing my friend's fish bowl for the time being, I really don't know what kind of tank, heater, fliter, or anything he really needs. Currently feeding him freeze dried blood worms a pet shop person suggested.
