Hello all, went to feed my 100 gallon outdoor aquaponics pond today and I found these black orbs all over the surface of the water. Any idea what they could be? My current stock is guppies, swordtails, and sarasa comet goldfish. Initially I thought goldfish eggs? I live in the FL keys where they pond temp is usually 80-85F, I would think it’s way too hot for them to spawn. Any input is appreciated!
