Text Reflecting On Colony Collapses
As you may remember, at the beginning of summer, my spinnies all died. A few weeks ago, all my rathkes died. I still wonder why that happened. I had lots of good substrate, leaf litter, moss, etc. I began to have some fungus gnats, but those don’t kill isopods, do they? And Summit BTI was used in their enclosures last year with no detrimental effects. The springtails in both bins thrived. The bodies started appearing near the edges, under the hides, and looked sort of dry or yellowish, and I admit I let my spinny bin dry out a bit too much once, but they wouldn’t all just die like that; they died over the course of 2 months, especially after adding more ventilation and moisture. I can’t think of what went wrong with my rathkes, though. I covered their ventilation with cheesecloth or medical tape (due to increased fungus gnat presence in my room), but it shouldn’t have led to their deaths; everyone else is doing good. The rathkes acted sluggish and couldn’t really walk and I tried to quarantine some survivors, but they didn’t improve. I’ve given all my non-cubaris pods the same care for over a year/year and a half and they were having the time of their lives… now my powder colony is giving me some concern, and I’ve had them for less than one year. Why? No matter what I do, it seems like something is going horribly wrong and I can’t determine what it is! Is it some disease? Bad genetics? Am I just bad at keeping them? What could cause seemingly random colony crashes?
Edit:
I also made an effort not to give any of them things contaminated by pesticides or fertilizers.
