I'm a new pond owner, I have 2 KOI and several gold fish. This morning when I went out to the pond, wrapped around one of the plants were what seemed to be thousand of little black eggs all enclosed in long slimey membranes. Are these KOI eggs? Looking forward to your answer, and in case they are, I read in another site how to try and incubate them.
Thank you in advance.
Nope, those are frog eggs. They can be a problem for fry (baby fish) ponds where the tadpoles compete for food, but usually in hobbyists ponds they are not. Frog and toad eggs are difficult to tell apart but it doesn't make a difference from an ecological impact standpoint. Frogs can eat fish and toads generally will not, tadpoles of frogs and toads are harmless to Koi and goldfish and may even be food items for the larger fish.
Koi Eggs, on the other hand, are laid during a "tornado" of springtime activity from fish larger than twelve to fourteen inches...Eggs are deposited everywhere, and are 1 millimeter in diameter, always pale tan color. Very sticky and very numerous. May have to look closely to see them.
