Just last week, I bought a half-moon Siamese Fighting Fish (scientific name: Betta splendens) and 2 Cherry Barb fishes (scientific name: Puntius titteya). In addition, I purchased a Tiger Lotus (scientific name: Nymphaea lotus; Family: Nymphaeaceae) for some colour. Since then, a Cherry Barb committed suicide by jumping out of the uncovered tank. Everything else is doing fine.
