I have a couple different colonies going and my newest acquired colony is doing something odd. This one was a split colony (I split in half) from a colony I purchased; I decided to keep these like pets -- they are in a 10 gallon aquarium, with heat pad, and care fresh (that paper pulp) bedding with cotton balls and some styrofoam pieces for pupating. Planned on adding decor later on as well, but wanted to keep it simple. I keep all of my colony between 75-85 degrees during the "cool" season and during summer have kept them up to 100 degrees (and they thrived!!!). The other half are just on the paper pulp and doing awesome, breeding, thriving, etc. This includes my other colonies. The only difference between all my colonies and this one are that they're in rubbermaid or a chest freezer, versus an aquarium. The ones kept as pets had a lot of beetles, they bred and most died (which I understand is the normal thing, lots of beetles, then lots of larvae at different intervals) and a ton of larvae showed up. As the other larvae are nearing pupation to adults, they would shrivel up and die instead. And it seems like it the pupae take a lot longer to turn into beetles; I pulled out some of the pupae and they shriveled up or did not 'hatch.' The only thing I can think of is that I'm not feeding them enough (scared of mites) until I am sure everything is good to go. No mites, no lice, no ham beetles, etc. Am I just caring way too much (because these are 'pets' and I just watch them) and paying too close attention or is there something going on? I've only had this colony for about 1 1/2 months. They are sprayed / misted once a day, sometimes twice, and only 2-3 times a week. All food is thawed out, frozen, dried out and fed. My other colonies are thriving. This one seems slower. Addition: I have been spraying ammonia on some food items, which I rarely do for this, but don't really fuss with ammonia on any other colony -- just the generic clear ammonia you get at Walmart.
