When I first started my tank three months ago I wanted to be ready for anything that could happen. I did a lot of research first and found so much could go wrong with a tank. But of course first starting out I was going to do everything right and have the perfect tank with no diseases or deaths. So here is my list of meds I have on hand: Maracyn, Maracyn-Two, Trisulfa, Tetracycline Tablets, Anti Fluke, Rid Ich, Aquari-Sol, aquarium salt and a Proquatics Bacteria Starter for after I'm done medicating and my biological filter has been harmed. All the meds have a expiration of three to four years from now and are kept in ziplock bags in a safe storage container. I know it seems like a lot of meds to have around and also was pricy, but I can't always get to a store if something were to go wrong. And yes I've had to use some of my meds as my idea of a perfect tank went out the window when my first fish died of swim bladder and another of a fungus all within one week of my first fish purchase. And of course other health problems have occured. My oldest son keeps asking me how can I enjoy my fish so much when I do so much work caring for my tank only to loose one now and then?Its hard for him to believe I simply love caring for them.
