I'm sure everyone would have nerites if they didn't lay those damn eggs. Scientists need to find whatever substance nerites use to keep those eggs attached to wood and rock and use it as an adhesive for buildings.
My vote is for Olive Nerites.. best little algae janitors in the world..
As to the eggs.. 1) my fish apparently like to eat them and 2)for some reason they were only a "problem" (since algae was killing every plant in sight I am hard pressed to call it a problem) for the first month or two.. A few months later nary an egg..
Don't know why but haven't had more than a sporadic batch (like on or 2, batches that is)in months..
The cure to me is certainly not worse that the problem.. They literally cleaned a hair algae/green spot infestation in days. That said they didn't do much for my Foxtail.. too delicate for them.
I would never not recommend them.. regardless of eggs..
