Betta Fish: I’m keeping brine shrimp 🦐

So far so good there pretty cool looking actually it’s a lot easier than I thought it was going to be . So I currently have a 2 gallon salt water tank nothing special a small heater and a small air stone and they are going strong I figured they would die right away but there doing very well. There not to keep so I have to not get attached there for my bettas .
