All geckos "3" were in the same cage, with the normal ficus benjamin and cork bark stripes. Temp low 70s, bed abeast. I keep "alot" of other leaf tails and this is the first time i ran into a problem. I have been pretty successful with hatchlings and eggs this year so far. Only thing i can say is some killer fungus got in the tank somehow. All my other tanks are fine, but keeping a super tight watch on them. I pondered along time about what i possibly did to the cage, and can't think of a thing i added or did different then my other 16 cages. Only thing i can maybe conclude was there was some fungus on a branch i added to the tank. I always get/cut branches from the upper tree limbs, and never pick up one the ground. I use a strict quaranteen and these have been in my care for along time. My last mossy in the cage i think is sadly going to die soon, as he dropped his tail last night and is now laying on the ground. This is so frustrating, as i have had no problems with my satanics, thank goodness, which im into mostly. I have had some geckos in the past just die of no known reason, as other raising Uroplatus have encountered, but this stumps me greatly. It just happened so fast, they developed these white little mold spots on there bellies and hind legs mostly. The first one had no signs of illness at all, which makes me think it started internally. Well i'll try to get a picture, all it looks like is white mold spots.
