My African Butterfly Eggs Keep Getting Eaten What Do I Do

[Seetrix]

Hey there my African butterfly cichlid eggs keep geting eaten or something there the ones that have the same blue reflector spots on them like the jewl cichlids. Theve layed like 5 batches now but every time I see them there gone the next day. Could a fish eat them. The parents chase every fish away that gets close tho I'm thinkin it may be my bristle noeses

Plecs are bad for eating eggs.If practical try and remove them for a wee while and see if they can get them to hatch.
