White spots

[N.Galvin]

Hi guys i have just been watching my tank and noticed some white spots attached to my tank are they eggs or is it something i need to remove.

The fish i have are:
5 red eye tetras
3 peppered Cory's
3 hi utsuri koi sword tails ( i think thats what there called, its the fish on the picture anyway)
3 amano shrimp

Any help would be great thanks

Looks like snail eggs. Do you have a nerite snail in your tank?

I have two red spotted snails i that i only got the other day

Should I remove them? I just read that they wont hatch as they need brackish water and they become difficult to remove as they harden

Nerite eggs on the glass are easily removed by an algae magnet. If left alone over time they will dissolve. I remove them from my glass but usually leave the rest to dissolve on their own. Some people go nuts when they lay eggs but I figure it's a small price to pay for the services they provide.
