Many years ago, in my marine biologist days, I studied jellyfish at the National Marine Fisheries Service laboratory in Oxford, Maryland. I’ve been fascinated with them ever since. I recall the first time seeing them in a large aquarium – in Monterey, California – and have watched as more and more aquariums have installed jellyfish setups themselves.
Jellyfish (yes, I know technically they should be called Sea Jellies since they are not fish, but old habits die hard) are not easy to keep in aquariums. They have very little control over where they go other than to backstroke up or down or side to side. Mainly they just go where the current goes. In aquariums that usually means straight into the filter. Nothing like a mushy, globular, nematocyst-laden carbon filter to gum up your tank.
So it took some engineering, some of which I developed myself in those good old days, to figure out how to keep jellyfish happy. And that makes me happy.
The aquarium also had the usual complement of sharks, skates, rays, and fish of all kinds. Not a bad aquarium at all, and one I’ll talk more about in the future. Check out the other aquariums I’ve visited all over the world.
