The liquid calcium would get watered down & they tend not to drink out of their water dishes much.
I would give it orally from a dropper or syringe, to make sure he gets the correct amount. Does he have any calcium issues?
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!
