A complete aquarium with all its accessories. I think its length is over fifty liters, maybe 50/60, I'm not sure. When you come to pick it up, you can check and see. It comes with: Ten colorful fish, I don't know their names. Two male betta/fighter fish. Two slightly larger fish, I don't know their names. Two snails. And a small fish that the seller told me was a tetra. I put shrimp in it, but I couldn't find them. I'm not sure if they ate them or not. It also includes: Heater Filter Special aquarium glass cleaner Decorative stone piece Four types of fish food Aquarium water conditioner/sterilizer And a beautiful colored night light. The camera is a bit bad, that's why the quality is not great. Price is negotiable. Offers below 400 will not be considered. I put a lot of effort into this aquarium.
