all types of coral...
LED, par38 bulbs (80-120$). 1 will be good enough to cover a 10gallons. under the bulb, SPS. indirect of the bulb LPS, zoas, softies.
if you want more coverage, evolution led.
I was also planning on using small live rock pieces live sand a power head a hang on filter heater. Then put some snails and peperment shrimp in there and keep corals on egg crates? What do u think?
i wouldnt do live sand just cause youre gonna want stronger flow. put some live rock underneath the eggcrate and you should be good. put a small fish in like gobies, blennys or something to keep the nitrogen cycle going
