My Sulawesi Gemmicintas are all onery at night..and I'm the only one in my family to ever go in there. Sometimes they get so worked up I have to cover the front of their cage if I plan to be in there for awhile..otherwise they beat themselves up hitting the front. I have one Dendro-Dendro that does this as well, but usually only after laying eggs. She then reverts to being ahy again. The 2 that are really irritable are 1.1 so gender does not matter when it comes to either my or their gender!
Out of the 3 ssp. of Dendros I keep the Melanota are by far the calmest..and largest. The pair I have pictured in an earlier post in this thread are 7' long and easily as big around as a big Cribo.
