Ocean World

Feel like there are few marine creatures. Let's fill the gap in sd1.5 marine creatures: sharks, killer whales, blue whales, clownfish, xx fish, octopuses, seahorses, sea dragons, squids, starfish, sea turtles, dolphins, penguins (just in case I forget how to draw on the ground), corals. Digging a big hole, please suggest what fish is needed below. The hint words are for reference only, there are things that I can't figure out as well.

Model recommendation: Maigou v7, or 1.5base, weight 0.65-0.75, redraw 0.4-0.5, redraw steps 10-20
