Do you find your weather loaches like to nibble floating Riccia? Mine have their little heads and mouths up in it all the time. I can't tell if they're nibbling the plants or goodies hidden within the plants, like maybe minnow or danio eggs. Since I don't plan on breeding either fish, I don't care about preserving the eggs. On the other hand, if my Dojos are getting good nutrition, so be it.
