Anyone have a clue what these are?

I've had these for awhile and could never find out what they are. Anyone have any ideas?

Almost look like blueberry fields

I wish I could get a better pic of them but that's the best I can do with my iPhone. The tank is due for new bulbs too so I may be able to see the color better when I change the bulbs
