First off- octopi aren't fish. (I've had a few confused students who were a bit confused on this point). Secondly, they're smart and beautiful- you can keep your butterflies!!
We were in Costa Rica a few years ago, and I willfully and blatantly ordered 'pulpo' (with a lovely garlic reduction- fits with the Raku theme). However, my wife informed me that I'd cursed myself. No more octopi revealing themselves beneath the waves. I was the enemy.
Hopefully if I crank out a few of these designs as a peace offering, I might be able to win some detente from the cephalopods.
I would have liked a little more crackle on the background in an idea world. I've been using cans of compressed air to induce crackle before the reduction stage. The problem is that plates are bloody fragile- if you get too haywire with the canned air, the whole rim might decompress and shatter.
An interesting note- the glaze on the bottom-most ridge-line is exactly the same as the glaze on the octopus vase. The difference- this plate went into the reduction chamber about 20 seconds swifter than the vase. A slightly enhanced oxygen feed- you get greens instead of golds and reds. Viva'le Raku!!
