I hope it was 1.025
Normal during cycling.
Good.
Increasing foaming could be caused by water additives, 'slime coat' etc. Keep the skimmer running ALL THE TIME... especially if you cycle with not previously cured rock stright from the shipment. Do not turn it off.
God forbid! Damsels are territorial and aggressive... Beautiful fish, but never use it for cycling if you do not intend to keep it later... You can cycle the tank with live rock alone - yours has already started the cycling: you see elevated ammonia. Everything is ok, do not make a mistake of many beginners and buy a fish which will bully other fishes later. Many if not most of the damsels bought for cycling tank land in the toilets because aquarists got them without knowing what fish they are.
