yea i know, kind of expensive to ship a $20 item. but if you want it you want it. if my tank was doing better i would split the shipping. had a lot of regular brittles but they died off. good luck in your search.
i have a steel stand and used rustollium top coat, its made for salt environment but not sure about wood. its holding up well.
prime it and paint a color of your choice.
i have 3 tangs already yellow, blue hippo and tomini. all around 4". but always wanted a powder, do you think the powder would be ok, i know they say their agresive in a 120 gal
i would put those type of corals on there own smaller rock and place or glue on your rock work.
if you place them directly on your rock work they will take over.
