I do have a UVB light on during the day for my snapper, he's out in the open during the day but he's more out and about at night. I'll give the D3 a try but I'll probably just end up using plain calcium and vitamins. His main diet is jumbo shrimp and chicken, I do feed him the shrimp with the shells on but I don't know how much calcium that's giving him. Again, I do cut calcium pellets and stick it into his food, but the extra vitamins might be beneficial.
How can I make sure I don't overdose on D3?
