Pond vs. Ramshorn eggs
Is there any way to tell the difference between the common pond snail pest eggs and the ramshorns snail eggs? I have both in a tank and I want to try and get more ramshorns but I want to keep the pond snails in check by removing their eggs if possible.

The clusters are somewhat different. There are some that are very symetrical and round where others have a distinct non round shape to them. There are so many clusters on the Anubias Nana that I want to remove those form the pond snail but keep the ramshorns.

Does anyone know how to tell the difference?

I will try to get a picture of them but it is not the easiest thing to do.

I've only seen pictures of ramshorns but the pond snail eggs are very hard to see. They are small clear blobs with white specks. Very easy to miss them.

I agree. I had an infestation of pond snails before and I keep squinting on the front glass for eggs. I was shocked to see several blobs with white dots and hastily tried to remove everything. I used the net to scrape them to make the job easier.

Finding the eggs is easy. I have another 20 or so on the glass right now. (I haven't decided to get my arm wet to scrpae them off yet.) I did notice a difference though and that iswhy I asked. I do have some baby ramshorns which is good, I haven't had any in a while.

Maybe it is as little as a gelatenous blog vs a thin sheet of eggs but I don't know. Am thinking baout tearing it down enough where I can boil the rocks, ornaments and pour some boiling water in the tank to kill the ponds and go from there.

Pond snails always produce blobs. I had ramshorns before and I never saw the formation of the clusters of eggs but I think you're right to point out the thin sheets. Those are possibly the ramshorns'.

Ok Trish, let's get some pictures to try an to figure this out. I will do some searching and see what I can come up with.

Well here is the answer I wanted. It turns out that the ramshorns are the flat clusters ones so I am kinda miffed now becaus eI have removed well over 100 egg cases in the past 2 weeks thinking they were the pond snails. I do have some more though so I should have a lot of them and happy loaches in about a month.

HERE is the site I got the information from. They carry most of the snails we like to either have or to feed to our snail eaters so it might be worth checking them out. I know when I am set up to I will be getting Colombian Ramshorns from them as they seem to the easiest to breed for me and can be fed any leaf type vegetable.
