If you ever try oyster do minimum 2 in a plastic mesh bag,hang so you can pull out and see if any dead, like in picture, seams to help. Pacific oysters one type can live in 65f-80f watersThose might be just a tad large for 14 gallon reef XD but now I'm curious...
I guess I'll keep throwing darts till they stick. No harm no foul since they would be eaten or tossed anyway.
