The Bird's Nest coral is a fast grower, great for beginners. This is Seriatopora hystrix, which does well with good stable water conditions and decent lighting. Mounting a frag like this to a piece of LR is easily done with Super Glue Gel.
Bird's Nest - Seriatopora hystrix - coral can make a very nice addition to a reef. This little frag had been bumped so many times in my tank, but continued to start new branch tips. Some fish find safe haven in a coral such as this one. Note the individual polyps covering the entire structure.
The tan colored coral with purple tips and green polyps is an Acropora valida. This was sold by Steve Tyree, and was labeled a "limited edition" coral. I decided I had to have a frag of it when he came to town to speak to our club. Due to higher Phosphate levels in my tank, a lot of my SPS had died. Some of it survived, and over time grew into a lovelly colony.
The coral in the foreground had its tissue eaten away by a Clown Goby!! Needless to say, SPS can be more than just challenging; they can be heart-wrenching.
Spotted online, I came across these great images taken by Shane Canellis of an acropora that is found in Australia. Hobbyists there call it the Dallas Acro, but it's real name is Acropora valenciennesi. Shane has been growing his colony for two years.
Hopefully some frags of this will migrate into the U.S. for others to enjoy.
This lovely SPS is a Surabaya Acropora sp. It is aqua-cultured in Surabaya, I was told. It has some lovely color to it and the shape appeals to me, and did well in my tank. The polyps are green, within a creamy-pinkish colored colony. Aqua-cultured means it was grown from brood-stock, rather than taking corals from the ocean's reefs. Often the cost of aqua-cultured is more, but they are more forgiving than wild-caught corals when it comes to settling into our aquariums.
This beautiful piece took a few weeks to get to this point. It is an Acropora secale, and originally the purple tissue was lavender. The Hippo Tang chewed on the tips for a few days, but overall the coral did very well. Within a month, it was encrusting upon a neighboring rock. Due to its dense shape, it can handle lots of flow.
Grown from a couple of twigs of Scripps Acropora - Acropora micropthalma, I have several small colonies in my tank a year later. Originally shared from the Scripps Institute's reef tank. This is a very fast grower, but rather frail. It is easy to accidentally frag it while working in the tank, but those pieces can be mounted elsewhere to grow out. Great coral.
Here is an early picture of an Acropora granulosa, identified by its shape and smooth skin. This coral is a prime candidate for red bug infestation, but I've not had that occur fortunately. As it grew out, what was interesting is the core remains darker green while all the new branches are lime green. Very pretty, although somewhat hidden by larger corals in my tank. This shot was taken from above.
This ORA Acropora sp. is named Pearlberry. With proper water quality, lighting and flow, it will grow into a very beautiful colony. Available from any LFS that sells ORA frags.
This SPS (small polyped stony) coral is pink Pocillopora - Pocillopora verrucosa. It has done quite well under 165w Power Compact lighting, and doubled in size in 10 months. I feed phytoplankton every other day, which this coral may be feeding upon. When a couple of small spots bleached, I broke them off to protect the health of the rest of the coral. This is not the fuzzy kind (although that could be due to fish nipping at it), but does extend polyps when the lights are off. Also called Cauliflower Coral.
