Good coral for my tank

[thompson2224]

What is a good non-photosynthetic coral for a 5.5 gallon tank? It will be transferred into a 20 or 50 gallon by mid may. Also what kind of maintenance will it need? I won't be able to add much supplements, what does it need to be fed and how often? thanks

Once it is in the 50 or 20 gallon I will be able to add all sorts of supplements
