Just found new eggs in my 10g hospital tank. Current tenants include 5 zebra danios and 2 "hitchhiker" snails. One snail looks like a ramshorn, the other I cannot tell. I don't think they are danio eggs, maybe snail?
definitely snail eggs. Danios are egg scatterers, meaning they drop them on the tank bottom which is why some prefer to have the bottom of a danio breeding tank in marbles... to keep the parents from eating the eggs and babies. They wouldn't have eggs on the side of the glass.
