@Androxian This girl has only recently come to me from someone who is having to leave the country. She is a bit heavy for my liking, to be honest. This is the one who has the horrible ulcer on the underside of her abdomen.
The girls that I have, who I have raised from spiderling/juveniles, are slimmer overall. I have two females that I have raised and two who have come to me from other people... both of those being far too heavy and both having the ulcers.
@VanessaS Ahh I see, well this is why I took your advice with my supposed female and stopped feeding them for a month, to slim the albo and the seemanni down. Now both burrows are webbed off so, I'm expecting a molt from both soon. It sucks that I can't see them, but now with two new slings, I still can watch progress in real-time.
I hope my albopilosum is spared the ulcers from my error. That would be truly heartbreaking..
@Tarantula Tech They are likely caused by the abdomen on a very overweight tarantula constantly rubbing against the substrate and other things in their enclosure. They are not found on individuals on the thinner side - only overweight adults.
Spiderlings and juveniles moult too frequently for the ulcers to form, but adults are moulting sometimes years apart. I have seen a couple of situations in the last few months alone of huge females splitting open during moults because of the ulcers. They can be deadly.
This is what the ulcer on this girl looks like...
@VanessaS Thanks for the wonderful sharing. My first learning of this possible danger of over-feeding. I tend to feed more to my Ts, resulting in most of them having very big rump. Very dangerous indeed. Thank you again.
