looks maybe like ick, are those particules that look like they're on the glass in the water or on the outside of the tank?

Particles in the water. I’m treating them for ick now but they are as lethargic as ever. Added some salt a couple of days ago but no change. Their fins are constantly clamped. Please help

Raising water temperature by 2 ish degrees is known to help.
Maybe try medication specifically for ick

Really not an expert on goldfish sorry
