Both are rather difficult to "handle". They are about the same size, 2-5mm and commonly found together so you might get both. When you pick them up with your hand or net, they tend to stick unless you swish them around to break surface tension / capillary action that makes them stick to you. Not a big deal really because they propagate rapidly with warm temps and good light.
Assuming here, but a zip lock baggie in a box w/ filler.
