Neon green toadstool (Sarcophyton elegance) are pretty, fast-growing and quite tough. They do like some nutrients in their water though, so if you are running an ultra-low nutrient system, they may not grow for you.
Green birdsnest are also super easy, one of the few SPS corals that are.
Pretty much any variety of Euphyllia (frogspawn, hammer, torch, in order of easy to harder) are easy as hard corals go.
Things to do as you explore more corals: Stability, stability, stability! Corals can adjust to high or low parameters of just about anything (temperature, alkalinity, calcium, etc.), but they generally do not like big changes.
Things you should have if you don't already:
Stable Salinity
- Aim for a stable SG of 1.026 or salinity of 35 ppt.
- Auto Topoff. This will make stable salinity a no-brainer.
- Invest in a good quality refractometer. The Marine Depot branded one is a great value for the money.
- Match your salinity when doing water changes
Stable Temperature
Invest in a calibrated thermometer. You can then adjust your heater to a known happy temperature for your corals.
Stable Alkalinity and Calcium (For stony corals).
A peristaltic doser is the easiest way to achieve this. The Bubble Magus is probably the gold standard here but the cheaper Jebao units work just fine. Large swings, especially in alkalinity, kill corals. I know aquarists who run their systems anywhere from 9-12 dKH. There seems to be no right answer here as long as the value is stable and you make any changes *slowly*, say over several days.
It's also advisable to drip acclimate new specimens so that you don't shock them.
Happy Reefing!
