I breed the Ghost San Felipes and they are very strong animals for me. Probably the best feeders of all of my rosys. Are you sure they are Ghosts? What price are you paying? The reason I ask is beacause the Ghosts are rather pricey for a beginner and from reading your below posts I see that you are new to keeping them. Just unusual for someone to start with ghosts. Are you buying just one? ..If so make sure its a female! The males tend to stay small and lean. Also if you ever want to get a mate and breed them a female will take 2-3 years to reach breeding maturity and a male will take only 16 months. Just want to make sure you get what you pay for!
