im getting a 29 gal because its the right kind of shape i want, but if i get dwarfs i might just make it a regular 30 gal. the fish in the 30gal tall dont have enought room 2 swimaround in, its like 3 ten gallons stacked ontop of eachother. and i would put the fish in the regular 30 gallon. would dwarf puffers be ok with a kribensis?
