I have a P. medusina plant. It is growing new leaves and had grease. It also has what looks like fleas living in the pot. It is the only pot amongst the rack of pings displaying critters. How I discovered it was via top watering. I saw what looks just like the fleas I have seen on pets. They hop. I know what aphids look like and they're not aphids. I tried taking a picture but couldn't get one. I did the drowning thing. Anybody ever experience this?
