You're the only one being rude! how can you expect to get the answers you need if you;re not even in the right place? What does it hurt to actually post the correct section? Why does that not make sense to you? I'm generally curious. I'm not people rude to you at all and you keep attacking us for trying to direct you in the right direction. You did get luck that some people who actually know about this subject as contacted you can help you but next time it is much easy to go to the correct section. That's all I'm trying to say. You can't be made at the information you're given just because you con't like it. If you do find a star that can be kept in the tank you have I wish you the best of luck and I do know that petco sales things for salt water upkeep if there is one near you if then you can just google search something like "salt walter aquarium kit" and you should come across the things you need.
