I have 3 in red eft stage. A 2 inch ish one and two little tiny 1 inchers. These are my first newts and salamanders. I noticed the one of the little ones on the other little ones back. Is this some kind of dominance thing? I haven't noticed any of them be aggressive in any way but they are mostly active while I sleep. I've found one of the little ones hiding under the same leaf as the big one. They all seem to get along and they were both atop a fern while piggy back riding. They were stationary and neither was doing anything to the other.
