Q: What can kill cresties in one night?
Posted By:


   I think I know what killed three of my four crested gecko babies. Two were only days old and the third was just hitting a month old. Humidity is good, and normally heat is good in the room between 74-76 degrees Fahrenheit. I don't usually use anything but room temperature to warm them. The one baby that did survive was eating very well compared to the others and was also a month old.

  Now what happened was that a window was left open on accident, and the night time temperature dropped to 60 downstairs and upstairs was 63 degrees fahrenheit. I'm pretty sure it was the temperature that killed off three of the four crested babies.

  However I wanted to know if there is anything else that could have killed off three mostly healthy crested gecko babies in one night. One of the three, the other month old baby had shedding problems and had been a bit weak out of the egg. The two four day old babies that died were both very healthy and eating well for their age. One of those two was found two days before drowned in its water bowl which I had to bring back with compressions and resucitation. The day before he had recovered greatly and seemed totally healthy again with no signs of secondary drowning. (I did fix the water dish problem where there were just slightly too few marbles in it. Their dishes already had marbles in them to prevent drowning but this damn guy still somehow managed to stick his head and nose under a marble.  >-< )

  More stuff to mention. They all four lived in the same bioactive tanks and set ups that my now adult older girl Narillo used to live in when she was only a month or two old. She grew up in them and had no problems with parasites or sicknesses in them. I was paranoid with my last living baby though and took him/her out of these tanks on the off chance something was wrong with the bioactives. I really don't think it was the bioactive tanks themselves though.

  It should also be noted that the one four day old who hadn't drowned decided that night not to eat at all. They are all eating pangea banana apricot mix and I have tried to feed them the tiniest of baby dubias. They showed interest but nobody had figured out how to eat them yet. >-< So was it the temperature alone that killed these three babies off? A combination of things? and if so did the fourth baby survive only because he was the best feeder out of the bunch? Thank you for reading and answering before hand.

a brief drop to 60 shouldn't kill them? are you sure it wasn't colder?

baby cresteds, like anything else, could have a variety of congenital issues that might kill them off young. the fact that they died all at the same time suggests an environmental cause. are you SURE about the humidity? it's very easy for tiny geckos to dehydrate. the 4th baby was a little older and probably handled whatever stressor it was better, but I would also watch him closely in the coming days.

one question...you have 4 geckos together in the same tank. not saying grow-out tanks are wrong, I'm in favor honestly as long as they are very similar in size, but how in the world can you be sure that a 4 day old baby is "eating well" in a shared tank?

The four babies were in four individual bio active tanks made from the same plants, clean up crew, and dirt that had once come from a larger bio active tank. I split it up to make the smaller tanks specifically to make sure the babies were kept seperated. I was actually able to split it into six smaller individual bio active tanks large enough to house only young geckos. They would be moved up into larger enclosures when they got big enough for them. That's how I knew they were eating well. One because they were alone in their tanks, and two because I was still hand feeding all of them early in the morning and late at night. The month old babies had gone down to just being fed once a day. 


Their humidity was maintained with misting every night so that they would be able to dry out during the day. I always made sure there were water droplets on the sides because I know that at this age they aren'tgoing to be finding the water dishes but rather drinking from droplets of water sticking to wherever they are at like the sides of the enclosure.

The fourth baby is still doing well. He or she eats more than their mother did at that age. It is currently in an even smaller enclosure for monitering but seems to be doing well. It even ate a number of calcium and mutlivitamin dusted baby dubias. It's a hog eating pangea.

The temperature is the only thing I can think of. In the morning when I checked it was 60 downstairs, but that was around 9am. It very well might have been lower than that in the earliest part of the morning when it gets the coldest. They are upstairs with me though so expect a few degrees more warmth up there.

that about has to be it. did you hatch the geckos yourself?

Yes I hatched them myself. They were the first four eggs of a new breeding female. It's her first laying season so I'm wondering if maybe they were a bit smaller and weaker because she is so new at this. Since their deaths they've been in my freezer waiting for me to do something with them. If it was a larger animal and not so small I would ask my teacher friend back at college to examine them. He's a herpetologist and might be able to help more with a dissection. However I believe they are too small. He'd have to be ultra careful with a knife.

I think what I'm going to do with the still living red boy/girl is keep them in the smaller tank. They seem to be finding the food on their own now as I've seen the tell tale open spots in the food where someone's eaten out of it. Plus there are little poops when I have to clean! :D At least one of my two keepers is still doing well.

Unfortunately the last baby has expired. It got sick, possibly from that earlier exposure to very cold temperatures I'm not sure. However it had mucus bubbles coming out of its nose and was not moving correctly, like it's skin was too dry even though the enclosure was plenty humid. Yesterday he/she looked to be fine but they did not eat either of the meals I tried to spoon feed them. The enclosure is being bleached now. Since I already had the other three in the freezer after this one passed I tried to see if the tarantula might eat it, and she did. There goes the circle of life. It almost made it to two months and was a lot larger than when it first hatched out. I wish I could have done more for the little one. Going to ask around and look up more ways of hydrating and feeding the youngest hatchlings. I want the next batch of eggs to have a better start than these poor guys. I just wish I knew what was wrong with this last one. Everything, heat, humidity, was fine and it up until yesterday was eating very very well.
