Angel eggs

[FishRunner]

hi,just noticed that my angels have laid about 100 eggs on my bio-filter wall, the male (i think) is swimming up and down them with a little tube sticking out of him, they are being very protective aswell an warding off the other fish, i'm very excited but nervous cause i hav'nt got a clue waht to do now i've heard to leave the light on 24hrs and increase temp to 32 is this correct and could anyone give me any tips?

many thanks
