Review on 🧽 Aquaneat Sponge Filter Set for Fry, Betta, Shrimp Nano Fish Tank - Pack of 4 by Alison Jackson

I woke up one morning and found a lot of koi eggs in our pond. The koi were already eating caviar, so we collected as many as we could and made a "frying tank" out of a large plastic container and air stones. In a few days we had hundreds of little fry. I needed an aquarium filter that doesn't suck in young fish. Bought a sponge filter and found it worked very well for my purpose. The filter did not pull the young fish into the sponge. In fact, the young fish liked to eat from a sponge. I soon ordered a cheap 4-pack to distribute the young fish to other tanks. Filters are easy to clean. As other reviewers have noted, the filters are large. I recommend this filter if you need an economical aquarium filter that doesn't have a lot of dirt in the water.
