Protecting fry from getting eaten

[tgf]

I have a breeding pair of discus in their own separate tank (probably 200L but if that’s too big unfortunately it’s the only available tank I have) to my main tropical tank. They seem to be laying eggs fairly often. Each time they lay eggs the discus place their eggs on the side of the in-tank filter and they generally stay there until they hatch. Say there are 40 or so eggs, about 25 of them get eaten and the ones that hatch live for a few days and then eventually disappear, most likely because they could’ve been eaten. I doubt they’d have been sucked into the filter.

My question is, once the eggs are laid, is there any way to protect them from getting eaten so I might be able to let some of them grow into baby fish and see how things go from there?

Its so hard to raise fry without the parents I would not worry about it.. Next time they lay tie some stocking around your intake... Or attach a sponge filter to make sure they dont get sucked up...

Good idea mate. Thankyou for that!

Buy one of these and put the sponge over the filter intake.

It adds both mechanical filtration while adding to the biological filtration capacity.

I currently have a Eheim cannister filter sitting underneath the tank as the main filtration system. I've had it running on this tank before and the breeding pair bred very successfully.

If I buy one of these sponge filters you've given a link to, is it possible to hook it up to the intake on the Eheim?

As stated mate, just slip the foam piece over the existing filter intake pipe. You don't need to use the plastic components. Buying one that has the double foam piece then gives you a spare.
