Other signs could be 1 gecko losing weight, being chased away from the food bowl, or having unexplained bites or scratches (I guess they really wouldn't be unexplained). I sold a pair of clutchmates to my doctor's office. They had been housed in a fairly small space with me and did fine. They were housed in a 40 gallon at the office but one started losing weight and had scratch marks. I had to take one of them back and re-sell. Now the scratched up one is living there alone and is doing great.
Based on percantages, how often would you guess this is a problem. I do not think I will have an issue, but I do like to be prepared As far as we could tell they're both female.
For the first time I have finally witnessed one female bullying one of the other females. It amazed me as they have been together all throough breeding season and I havent had a seconds worth of a problem outta them, now all of a sudden one just picks on the other. Oh and yes as soon as I saw this I seperated them. These two are the first ones I have had a problem out of. I keep roughly aorund 45 adult geckos and most of them are kept in small groups. This is speaking completely about females.
the laying on eachother is the one of the first signs.. the one with it's head on top of the other is the dominant one and should be watched closely. I had a pair we kept together for about a year and out of nowhere the larger of the two was losing weight..
then we separated them and she's a house once again..
we keep all of ours separated at all times (aside from breeding of course)
