BoulderFish. A very distant relative of our old chum BoulderGirl, he fulfils a similar role in all & sundry aquatic environments. That is, he shadow-dances dimensional insurrections into being and, on a good day, he'll be able to call up a watery Sipapu . If you're very, very, very lucky, you might find him lurking temporarily in the depths of your water tank. Offer him a little cake or a few drops of vodka and he'll see what he can do.
A word of caution. Do not overdo it with the vodka. He's extremely susceptible to high-proof spirits and you don't want a riotously drunk and possibly disorderly BoulderFish on your karma, believe me.
And here’s a wee link for your delectation and instruction in case you didn’t know a Sipapu from an ordinary hole in the ground:
