There are a very few corals that require no light. Sun corals and carnation corals are two I've been able to find on google. I don't think you will be able to find much in the 1 1/2 wpg
range. Maybe you could get another set to make it 160 total watts which would be a little better. Maybe then you could have shrooms
, polyps and maybe zoa's. You can forget the anemone's though. I'm pretty sure none of those could survive that lighting(except maybe aiptasia and oh that's bad).
I know lighting can get expensive but 4 foot shop lights are only 10$ at walmart and you can get another 80 watts of good bulbs for that and then you can save up for the decent ones. That's what we did.
