over the last year I have had 3 tarantulas seemingly die all from the same thing. I had a g. Pulchripes, a. Chalchodes and most recently a lasiodorides striatus suddenly enter a death curl and eventually die. None of them were matured males, so I don't think it had to do with age. I had kept the pulchripes and striatus successfully since slings with no issues and the chalchodes for several years as well no issues. I provided hides, access to water (misting once weekly and water dishes for when they want or need more) and food. Rusty reds and crickets as feeders. I notice them drinking and their abdomen all look normal and healthy at time of death. I checked for nematodes and saw no signs of them either. I also dont think all my Ts just end up getting impacted either. One day they are fine and then the next day they are walking oddly and then in death curl soon after. I continue to supply food which is not eaten, and water which the tarantulas still seem to drink. But eventually settle in a spot and end up death curling and dying. I am not sure what else to try and I am unsure of what the issue is. Any ideas or suggestions would be appreciated I no longer have Ts but this situation has perplexed me and I am searching for some kind of potential reason as to what happened.
