Cleaning up microworms

I’ve just started feeding my larva today they already had some daphnia breeding inside their container and producing some baby daphnia for them. My daphnia culture seems to be very slow in production, so I don’t want to harvest too many right now. So I put some microworms in today. I wanted to know how much I needed to clean after the microworms. They are so small that it is not really possible to suck them all out after they die. Are daily water changes necessary? are microworms as soiling to the water as brine shrimp?
I feel like changing the larva’s water everyday would be stressful for them.

On a side note I have some larva with very small heads and only one eye. Has anyone had any experience with this type of deformity? One of them died today, it actually looked like he was ripped apart. Should I expect the rest with this deformity to die as well? Should I separate them from the other larva?

Thanks

I would use a turkey baster to remove the largest part of them. If you can´t get them all it´s not a problem as it is unlikely that small amounts of them will have an impact on water quality if the containers have a decent volume. The use of natural plants would be benefitial in such a situation since the small amounts of ammonia produced as a result of the decay of the unremoved whiteworms would partially be used by the plants. In conjuction with partial water changes it would be almost risk-less.

I cannot give any useful advice on cleaning up microworms as I have not used them. The malformed axolotls sound like a recessive mutation called pin head which is usually lethal. Ambystoma Genetic Stock Center
