I have been testing the waters on some LPS corals myself. I would recommend some specimens that are known to handle low- medium lighting. (Once you turn on the high beams, you better know what your doing.)
Meteor Shower Cyphastrea - This has been my unofficial PAR meter. Talk to Enzo under Livestock for sale. Pls. tell me if you find a branching Cyphastrea (Cyphastrea decadia) anywhere. We may have to do a group buy with Reef Corner.
For SPS, I would think the Ponape Birdsnest (Seriatopora Hystrix) which is strangely also known as yellow birdsnest . It provides very noticeable indications by changing color and bending it's sharp growth tips. It grows skinny, so the growth pattern may also be telling of flow issues. If you grow a stag that's symmetrical and nicely colored (anywhere from yellow/green with purple/pink tips to hot pink), then your setup is on point. Obviously, you take cuttings along the way. : ) If your tempted to get the ORA Green birdsnest, which is more demanding, go for it. You can use it for comparisons as well.
As for the first Acro, I will probably go with the Garf Bonsai, which looks like the Miyagi Tort to my inexperienced eyes.
