My puffer doesn't go after the green as much as my 405nm or the 650nm, I am afraid to try my 445nm, I don't want to blind one, if it it can.
My current 445 is "only" 150mW.

My friends' fish mostly swim away.
I've been able to attract fish to the surface of the local lake with a 100mW green. But these fish (catfish or something) are much bigger than your typical Petsmart variety.

Haven't tried at the lake. In the aquarium they chase the dot. I think my 445 is around 700mw it's supposed to be 1w, I don't have an lpm, so it's just guess.

Hmm, Do you know if the O rings will hold to around 100m? Also, I have never even heard about that kind of switch. I will have to look it up.
The switch is activated by a magnetic field brought nearby.

Also ,I think 100m is only like 150psi... for a well designed Oring gland that is nothing.
You can hold probably 30X that much pressure with the proper oring.
