I'm a new aquarium owner and I currently have a still-cycling 5.5 gallon tank. I was going to get a dwarf puffer but I'm not sure that would be a good beginner fish (also the thirty dollar shipping is a pain). I was thinking about maybe 3-4 pygmy corys and some shrimp/a snail, but I'm not sure if that would work out. Any advice or stocking suggestions are welcome!
