What is the best animal to put in a tank with a Beta fish to control algae?
If he killed the snail, you might just be out of luck. One thing you can do is ask for the little snails (that reproduce like crazy) at a pet store. Most pet stores have these in their tanks (like at Pet smart they are everywhere). They will usually give them to you if you ask. The positive is they will reproduce enough that I don’t think he can kill all of them at once, so you may have a nice stable amount of them in your tanks at all times. The negative is they may possibly devour your plant. But this is true with any algea eater you place in your fish tank. Because algea eaters eat plants. Algea is a plant as well. If it is a small aquarium do not add a plecostomus. These guys get 18 inches long, and they grow quickly. So in a few months he wouldn’t be able to move much and your plant would def be gone. I suggest trying an Otocinclus algea eater. They only get 2 inches big. Your Betta may have killed the snail because he saw it as food and it can’t run. The algea eater can. *******B
