So it turns out that trying to get live rock when you live in a small town is trickier than it seems. And ordering online is……..an adventure. I went ahead and ordered some live sand to start cycling the tank. I’m still not sure the jellyfish aquarium will require much of a diverse bioload, but I’ve never tried to keep a tank with only one species in it, and I don’t know how delicate that might make the eco-balance.
