My Axolotl are about a week and a half old. I have been feeding them brine shrimp. The first batch of brine shimp lasted a long time, because somebody told me to put it in the fridge in between feeding. This worked fine. My second batch of brine shrimp hatched, I fed the axolotl twice yesterday, and then put it in the fridge. Today, to my horror, the shrimp are all dead. 99.9% at least, I see a movement every so often. What do I do? I currently have eggs being made, but they won't be ready for another day. I have frozen bbs. Would the axolotl eat that? Or do I give them the recently dead bbs, with maybe a few live ones. How long can they go without eating? Is 20-30 hours ok?
