Whose Are These Eggs?

[kajones]

I've just found these eggs on the glass but don't know whose they are! In the tank there's 2 corydoras, 2 bristlenose catfish (juvenile), 2 otolinctus catfish, a little glow light tetra (i think that's what it's called) and guppies ( I know they're not responsible!. Also snails but they don't look anything like snail eggs, any ideas anyone?

I've just seen one of my corys depositing more eggs! I've removed some of them cos the guppies were eating them, I've put them in my nursery tank with guppy fry, hopr they will be ok. Funny thing is,i thought both corys were female!
