With my new 125 gallon im doing a fish only tank, hopefully an aggressive tank. Are there any types of fish that cannot live in hyposalinity constantly? What salt level is your tanks yet at? i understand a dragonet could live, but its food wouldnt
i was told eels cannot get ich, is that true of sharks and rays and other scaleless fish aswell?
and finally, i believe i was told fish/inverts dont sense red lighting, is this true? is it another color?
im trying to find which lense filter to get my flashlight

What kind of hypo are we talking here?
My fish ALWAYS reacts to the red light. Most of the inverts did not.

I hope that you are referring to hyposalinity as a way of ridding fish of parasites and not for them to live in it constantly, as this is the vibe I am getting from your post

i didnt plan to leave it that low constantly, no, but in fish only tanks, do you normally keep the salinity a bit lower?
ive always had inverts so im not sure if thats common or not
