I've been avoiding updating this topic for a while but I'll bite the bullet. Just before I went on holiday, leaving the axolotls in the care of my dad, I bought a bag of glassworms since the bigger babies were getting to the size that they needed something a bit more substantial than daphnia. Unfortunately, upon my return, I found that the majority of my babies had died. All, in fact, but the container of small babies and a few in the main nursery tank. Upon sticking some water under my trusty microscope, I found that the glassworms were RIDDLED with trichondia and chilodonella. I was livid. Thankfully, the ones that were only exposed minimally seem to be doing fine and I'm doing 100% daily water changes on the others. The majority are eating ok and look as though they'll pull through but I only have a small handful left. In fact, about 10 leucistics and 2 wildtypes. The last albino died over the weekend.
Of course, this incident has been deeply disappointing since they were all doing so well up until that rouge bag of glassworms but to every cloud, a silver lining. My home daphnia culture is thriving, so when I get the courage together to try breeding again, I need never buy from an untrustworthy source. You never realise just how unhealthy store bought daphnia looks until you culture your own. Instead of being slow and peach coloured, they're too fast for me to catch with a net and dark brown, full of eggs! I'll get some photos of the remaining babies (and a daphnia comparison) later on
