Pink Galaxy (Galaxaura rugosa) is a semi-rigid dome shaped macroalgae that is just incredible looking. Growing to between 3 and 4 inches in diameter it can be attached to any surface in your tank. It is easily kept, requiring little light to survive. With brighter lighting it will take on a reddish color, in 1-2 watts per gallon it will retain its pink color. It does not have any specific circulation needs, grows at a moderate pace, and should be kept in your display tank rather that just as a filtering species. While it is not at risk of being devoured by snails, herbivorous fish and sea hares may eat this plant. While it is semi-rigid, you should be careful when handling this macro, as you do not want to break a branch and distort the perfect dome shape it grows into. There is very low risk of ph disturbance with this species.
