yep your sun corals look healthy... placement is anywhere (low light or not contrary to popular belief) and in low to medium flow areas not high flow...
the biggest pain is you have to feed them regularly... once every 2-3 days is minimum to keep them alive... every 1-2 days to keep them happy...
best way to feed them is eyedropper type to each polyp... they'll swallow and in a few minutes want more... so it's a 15-30 minute process... I go through one cube of
frozen mysis or enriched brine shrimp (with cyclopeze)... you'll need to kill the pumps though and shoo away any shrimp that would seize the opporunity to steal the food from them...
now the reason people say low light is so the polyps would come out... they naturally feed at night and that's when they extend their tentacles.. however, if they 'smell' food, they'll extend polyps out in a few minutes to feed... if you do this at the same time every day, they'll start being trained to open when the lights are on (if that's when you feed)... hence why placement for light isn't important, IMO and IME...
high flow ticks them off and
polyp extension isn't that great in such environment.
don't know much about chili
