Lol there was definitely a time when it soured my interest in my tanks. Our tanks are microbial soups, it makes for a flourishing ecosystem but some level of risk with that is innate. You can get some extremely nasty infections from an aquarium. But you can get the same ones from preparing seafood, swimming, fishing etc. Millions of people in the US alone do these things every day yet serious infections remain very rare, despite the vast majority of those people being completely unaware and taking no precautions. Just don't go digging in the sand with open cuts, wash your hands well, keep water away from mucous membranes and if all else fails, know when to seek medical help
