I would recommend either setting up a cherry shrimp aquarium, or trying and save up your money and get the proper equipment for setting up a betta aquarium. Best of luck.
I would not even recommend it as a shrimp tank. Red cherry shrimps require stable water conditions too, and they are more sensitive than many fish species to the sudden changes in the environment. A 2.5 gallon tank is too small to have a proper filter and heater, the remaining room is too tiny to have enough water for stable conditions. I wouldn't have a shrimp tank of less than 5 gallon, and that is the minimal size. A 10 gallon is recommended.
