Acropora corals are one of the primary reef builders in world's oceans and they are highly sought after by reef tank hobbyists for their remarkable growth rates and intense colors. Fragging acropora can be a fairly lucrative hobby if you have a good base to start with. You can trade acropora coral frags in at the store for credit, trade with other reef tank keepers and even sell them online. There is a demand for acropora, especially tank grown acropora since it helps lessen the burden on the reefs and most educated hobbyists nowadays will pay a little more knowing that it was captive grown.
There are literally tons of different species of Acropora (pronounced ah-crop-or-ah or ak-roh-pohr-ah). You can find them sporting colors all across the board such as baby blue, green, purple, brown, yellow, etc. Care wise the majority of the different acropora species require the following:
High lighting levels
High, variable and turbulent water flow
Stable water temperature - 75°F - 82°F (24°C - 28°C)
Very low levels of nitrate and phosphate - these two can really decrease the growth rates in acropora
Stable and high levels of calcium (400 - 450 ppm), magnesium and alkalinity
Keep marine pests such as crabs and acropora eating nudibranchs to a minimum
