Welcome to FishLore! It's great to have you with us! Please click on the link in my signature "FishLore Articles for Beginners" to help get you started. Bigger tanks are easier to maintain. Cycling and maintaining a 2.5 gal. is quite a challenge because you are so limited on what you have to work with. The bigger the tank, the more water you have to keep everything stablized. Small tanks can go downhill quickly, and you usually have less time to know something is wrong before you can do anything about it. Getting a much larger tank is a great idea. A 20 gal. long is a really great size tank to have!
