Every fish keeper that has kept fish for any length of time, and especially if he/she has maintained multiple tanks concurrently, knows that having the right tool for specific tasks can save time, effort, and frustration. I can't count the number of times that I started some task only to realize that I simply didn't have the right tool to do the job. For that reason, I've put together a short list of tools that your fish keeping toolbox should not be without. This isn't exhaustive, but having these items will make setting up and maintaining your aquarium much simpler.
These next items aren't really for a tool box, but they will be needed at some point in your fish keeping travels.
