Bristlenose Kribensis egg-eater

[Tyrongyde]

Hi guys,

I currently have a breeding pair of Kribensis in an 80L (20 gallon) tank mixed in with two lacustris rainbows, a few guppies, 3 bristlenose and 7 harlequin rasbora. Yesterday my kribensis produced their first batch of eggs (around 50) against one of the pieces of driftwood (exposed with exception of a few plants). The males seemed very relaxed around the eggs while the female took to guarding them with her life. I woke up this morning to find all bar ten eggs had been eaten. Immediate suspicion is that my bristlenose have had a midnight snack on them. Does anyone have any suggestions in creating a set-up to allow the kribensis to stand a better chance of defending her eggs? I currently have only one tank so moving fish/eggs is a bit of a mission. My tank is also a bit too small i feel to place in a divider to stop the bristlenose accesing the breeding site.

Thanks,

T
