I looked in my sump earlier to see thousands of these horrors crawling over the floating plants. Does anyone know what they are, or how I can safely move them on?
They look like aphids to me. Try washing the plants under running water to reduce loading. Will have to repeat as needed. Every female is born fertilized and pregnant and so are her offspring. (There are males & females but the complete life cycle is complex).Does anyone know what they are
Have you got fish in the tank? If you have just wash the Aphids (with sprayed water) into the tank and <"fish will polish them off">. Often you can just turn the plant upside down and the fish will pick them off the submerged leaves, but I understand that might be difficult with Eichornia crassipes, due to its buoyancy.Would periodic spraying of a vinegar solution eventually eradicate them?
