I find that if geckos eat too much (at least with my leopard geckos) they will regurgitate and often "learn their lesson". It sounds as if you're on your way to becoming a day gecko sanctuary!
No regurgitation yet. I’m thinking that it’s time to either move him out of the hospital terrarium into a bigger one, or release him back into the house. But now that there’s a big intruder hanging around I worry they will fight. I wish I only had to worry about one. I feel so bad that Mi-Chan can’t enjoy pure sunlight in his old area now that it’s overtaken by the fat one (his name is Fat-Chan) It’s the same one we caught and released outside the condo. Apparently he made the 40ft travel and then climbed back up 6 stories to get home.
