Otocinclus catfish are great Betta fish tankmates

Plecostomus catfish are two types of catfish that do well in tanks with Betta fish. Corydoras and Plecostomus come in a lot of different species, but you should stick with the ones that stay small. When we say "smaller," we mean that the corys are about two inches long and the plecos are less than five inches long. It's important to say how big the Betta aquarium is. This guide is for a Betta tank that is at least 20 gallons and preferably more. The better it is, the bigger the community tank is. This gives the corys and plecos the space they need to look for food and gives the Bettas room to swim around and show off their beautiful fins. Since Corydoras swim in groups, it's best to buy at least four of them at once. If you choose a Plecostomus, you might want to order just one. Algae eaters, also called Otocinclus catfish, otos, or dwarf suckermouth catfish, are another great cleaner fish that gets along well with Bettas. Remember that when you order Otos, you should get at least three or four of them, since they are also schooling fish. Also, don't forget to give them more food, like algae pellets, because they will eat all the algae in your tank, leaving it clean, and you don't want them to go hungry. Even though you might not think so, snails are great neighbors for Betta fish. They are safe and colorful, and they make the tank more interesting. Mini Golden Rabbit Snails are one of our favorite suggestions for Betta fish tank mates. These snails come from Sulawesi, Indonesia, which makes them one of the rarest snails in the aquarium hobby.
