Abyss Anglers: Top of the Class

Using an Inky Black potion here makes the schools pop out really clearly from the environment, in case you have trouble spotting them. Just don't expect to be able to see anything else in the process! :D

I have been disassociating for 30 minutes.

Path:

Go left, grab the two stacked together above the steam vent.
Head right, grab the one by the rock.
Head straight, grab the one above the flat rock.
Head straight, grab the one in the eye of the coral.
Head far left, grab the one in the eye of the coral.
Head straight, grab the two in the big coral (one low, one high).
Head straight, grab the two in the big coral (one low, one high).
Grab the last one above the steam vent just to the right of the big coral you were just at.

That's a quick 11 in under 2 minutes, depending on swim suit speed and usage of the dash mechanic. Be aware that dashing through the schools may not give you credit for collecting them, so slow down once you approach the schools.

All told, you can be done with this achievement in about 30 minutes. Don't fret.
