Low light coral recommendation please

I am assuming from the description the light are standard aquarium lights or T12's. With the right bulbs they could keep some corals.

I currently have and have for the last 9 months a standard 18 watt light on my Small seahorse tank, in it I have mushroom's
(See picture below) Zoas and a couple of ric's and all of the above are thriving just fine and that 55 is only 2 inches
deeper that mine. And I think its Omard that has a 12 gallon Nano with only 24 watts of light and he has tons of coral in
it that are doing great.

Very few Gorgonians require feeding, most are totally photosynthetic making them a beautiful, easy to keep soft coral but
they would require more light than what is currently on that tank.
