Well thats good that you have experience with delicate tummys. The rosys seem to do better not having a water dish in their cage. I used to water them weekly or monthly but since I stopped the regurges got better! Now I only keep water with neonates and gravid females. Works fine for years.
:from emerald tree boas to surinam BCC, I have never had a regurge. I was a little worried because with all the snakes Ive had, this is my first and only rosy boa, and its a weird little snake. I mean Ive seen em before, and I know what they are, but its weird to have one. Their heads are so tiny, and their scales so... i dont even know. But i named this little mexican boa "Jose Jalepenio".
