I have this 30 gallon tank laying around and My dad and I thought it would be cool to use it instead of it just collecting dust. Originally, we thought we were going to aquascape this for a Betta tank with some cardinal tetras and some amano shrimps but after doing a little more looking I came across pea puffers and puffer fish in general. I am sort of at a crossroad with ideas and decided to ask you guys to see if any of you had some interesting ideas! I was thinking some sort of freshwater puffer would be cool but i understand that most of these guys can get fairly large like Mbu's and fahaka's. Are there any other puffers that could be a good fit as a centerpiece for a 30 gallon?
