Ok, so i decided a Dragon Fish was not for me ( or my ten gallon tank)

So im looking for another kind of "oddball fish".

Yesterday i was in El Paso and i was at Petsmart ( i really like this petsmart they take EXELLENT care of thier animals) and i saw some really cute dwarf freshwater pufferfish.

They were only 3 bucks so i was going to get one but i wasnt sure of thier care.So i didnt buy one.

Will just one be happy in a ten gallon by itself ?? I know they are agressive so i wouldnt be able to keep them with my guppies, betta and neon tetras would I ?

What kind of food do you feed them ?

And how big exactly do they get ?
