Which corals would life under 15 watts???

So I would like to know if there are any corals(shrooms/softies/leathers/polyps) which will live under 15 watts of light in a 20 gallon high tank?

TIA

 

Pretty much none! but mushrooms might be ok I do not know since I always use 80w on a 30g long and it was fowlr

 

chili coral, gorgonians (for the most part), some sponges,

 

Cauliflower, or chili but they require a lot of food in the water column and target feeding.

Well........None really. 15W standard lighting is nothing. If you want corals, I would buy two of these and put them side by side. That would take care of business. JMO.

I was asking this question for my uncle. He just wantd to know if he could like have one coral(he does not want a full blown out reef or anything like that. Just something to change the FOWLR tank that he has now.

 

you would have to put what ever coral it was very high in the tank like right above the light. just get a nice power compact it will make the tank look a lot better also and the fish will glow brighter

 

you can do a chili. Your uncle would have to feed it phyto or some other fine filter feeding food. I think it would do great.

 

Youcould do sun coral too - pretty much anything that is non-photosynthetic. However i find these corals the more troublesome to look after.
