Montipora and birdsnest are great beginner sps. They are generally known to be more forgiving than acropora species. They generally need a very stable tank with no phosphate and very very low-none nitrate. They generally prefer high light, high flow, and higher calcium levels. It is important to make sure that your alkalinity, magnesium, and calcium stay relatively stable. I have been maintaining my sps tank at:
Ca: 450ppm
Alk: 2.5mg/l-3.0mg/l
Mg: 1400ppm
NO3: 0ppm
PO4: 0ppm
I use LED lights and have had pretty good luck so far. Everyone has a few bumps here and there, but you'll get the hang of it. I have an orange encrusting monti frag you can have if you want to come get it.
