I have found a little trick that has at least got Dewi having a nibble - to make sure that the greens are piled high enough so they are somewhat higher than the bowl edges so he can see them easily when on the ground.
I have now put his greens in a very shallow, glass saucer, rather than the exo-terra dish I bought. He can see them properly now, even if he is lay down.
I give them a spray now and then and he seems to munch more often.
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!
