Hissers sluggish then die

[lonelyronin]

My hisser colony is having a problem - I have been finding that one or two at a time will become sluggish over a weeks time - to the point that they will barely struggle when put upside down - then they die. Its been going on for about 2 months.

Any suggestion? comments?

Heat is 85 degrees, they have a humidity hide, fresh food along with dog and cat food. Nothing have really change from before this started happening.

How about the water source?

I use gel water - cleaned every second day

Are all the dying ones adults? It could be that their generation is just dying off.

I only had two original hissers - all these adults are from the first litter (is that what its called?) which is only 6 month old. I'm going to try misting them more, maybe they need more humidity - hopefully I can save the rest.

The same thing happened to one of my dwarf hisser colonies, at first I cull any that show the symptom, but that didn't work they just keep dying. Finally, i selected a few strong ones, and culled the rest. After 2 weeks of quarantine, I put them into another colony of dwarf hissers, and they're fine since then.
