hmmmm ok... Is there any species i can care for in a 30 gallon tank.. (EXCULDING THE DWARF PUFFER.. SEEN EM IN PETSMART. TO SMALL). Concluding from the size they get to be.. Im aiming toward 4 figure 8's (with planted tank)... In conclusion to you statements, it seems the green spotted puffer is a bit to big and agressive.
