Awesome small aquarium filters perfect for a 3 Gallon tank
I wasn't sure what to expect at 6 for this price but these were the perfect size, last just as long as the 3pack I've been buying at the store for this same price! For that I'm sold, what's good got my beta Ravi, is good for me!He's stoked that his aquarium is staying crystal clear! Ravi recommends these filters
