Hi, I have 3 new Axies that I got on the weekend. Because they had already eaten on the Saturday I didn't feed them until the Sunday night. They were not remotely interested in anything like bloodworms, pellets, or even worms. However each was more than happy to eat a piece of fresh (not smoked) salmon. Since then, 2 have not eaten anything else..! 1 is still more than happy to eat salmon...nothing else. When should I be starting to really worry about the lack of eating? The last time they ate was Sunday night. It is now Wednesday night. I've been keeping a log of all water condition and they all seem fine and they have a chiller as well set at 16 centigrade...I'm worried as I spent nearly $1000 to make sure I had everything possible covered. Thank you
