So I’m redoing my 5 gallon betta tank. I’m putting in CaribSea Super Natural sand as the substrate and will probably do a crypt or fake plants as the lighting is low in it. I also plan on adding a MTS to help stir the sand and possibly a nerite or mystery snail. That being said, what are the best HOB filters? Or are other filters better for a betta tank? Right now it has an internal tetra filter and I hate it lol. It takes up so much space inside the tank.
