boss curious lng, pde ni cla ibutang sulod sa aquarium?, planning to put this in a tank of piranhas .....
pde kaayo ibutang sa aquarium sir...if naa nakay tanum you dont need any aerator anymore, only filters nlng...
i dont know about piranhas sir pero carnivores mana sila...try to research lang sir what kind of fish you have ug pde bana sila sa aquatic plants...
