It's been a few years since I've started mine but I think it took about a month for me to start feeding out of it SOME and then I want to say it was w/in 2months that I was feeding out of it exclusively (for my geckos).
I just set Swordtail's timer for his bath and paused it so I could actually fill his soaking bowl up and he crawled over my phone and canceled the timer
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
