Blue Eggs

[richw]

Hi all,
 
Had my tank populated for about 3 weeks now and did a 40% water change this morning. Just checked out the tank and I've spotted a cluster of about 30 blue dots on one of the pieces of wood. I presume these are eggs, but I have no idea who they belong to. They're quite exposed and all the guppies and five banded barbs seem interested in poking them!
 
Contents of the tank:
 
8 five banded barbs
1 bristlenose plec
8 guppies
1 pond snail
1 unknown snail (light dots on it's shell)
 
Any ideas? If they're snail eggs I want to get rid (I'm only keeping the snails in the tank because I'm getting loaches in a few months and thought they'd be a nice treat)

Well given that guppies are livebearers and the barbs are egg scatterers it's not them.
 
Bristlenose eggs, I believe, are yellow.
 
So I'm going to go with a snail, but I've not seen blue ones before. Could just be the way it's catching the light though.
