Sinking fish

[Welsh_Woman]

My tank water is green and ive been trying for weeks to get rid of it, today now i seen all my fish are sitting on the bottom of the tank, apart from that they seem ok, no heavy breathing or anything. why are they doing this?

what are your water params?
I'm guessing, as you have green water, your nitrAte levels are very high
thus causing the fish to become ill.

i'm changing the water soon anyway, but they look fine...its weird,

by soon I hope you mean now.
the quicker you perform a water change the better
in this case I'd recomend 40-50% now and 20% in two days time.

good luck
