I have masses of Riccia in my tank so decided to thin it out. Rather than throw it away I put it in my spare tank which is currently fishless. Looked in this morning and saw at least three small fry - growing them on to see what they are. I expect they'll be either neon rainbows or emperor tetras both of which spawn very frequently in my main tank.
In future I'll put any plant trimmings and Riccia in a tank for a few days to check if there may be fish in there.
