Second guessing myself re: G. Pulchra juvenile premolt

Hello everyone,

I got a lovely G. Pulchra juvenile female (1 yr old; 2") about six weeks ago. The breeder told me she had last molted a month earlier, so in late October. She's my first tarantula and first pet arachnid, so I've never been through the molting process before, and I know these slow growing spiders can take their time going through the process. A week after I took her home, she settled in and started eating like a champ. I was feeding her mostly crickets, twice per week. I started her on 1/2" crickets, then switched to 3/4" adults. I also fed her a couple mealworms.

Ten days ago, I put a cricket in her enclosure, and for the first time she seemed to have no interest. At one point she was standing right over it, but just turned and slowly walked away into her burrow. Eventually I crushed its head and left it there for her overnight. The next morning she still hadn't eaten it. It was the last cricket in my stash, so I tried to feed her mealworms for the next couple days, to no avail. She would stand over them while they were wriggling, and I would have to periodically use my tongs to prevent them from burrowing before eventually taking them out, crushing their heads, and putting them back overnight. She didn't eat one.

Wondering if she might be in pre-molt, I bought two adult crickets from a local shop, crushed one's head (if she was in pre-molt, I didn't want to have to try and fish a cricket out of her enclosure) and left it by the entrance to her burrow overnight. She didn't eat it, and when I tried the same thing with the second one a few days later, it was also no dice. Combined with her disinterest in food, she displayed other signs of being in pre-molt, including: spending most of the time in her burrow compared to before, not climbing the sides of the enclosure, and being far less active. She also has a big ole abdomen, but the skin underneath hasn't darkened.

One thing she has been doing since she stopped eating is a lot of excavating at night. She's digging her burrow much deeper and leaving the substrate against the sides of the enclosure. Although her burrow's top half is a half-round of cork, partially buried, weeks ago she dug a little tunnel out the back, which I call her back door. So, a few days ago, she plugged up the back door with substrate and I thought to myself, okay, she's definitely in pre-molt. I've offered her mealworms every few days, but she never eats them.

Then this morning, I opened the shade and she was out of her burrow. She spent the whole day out like she used to, snoozing in the sunlight. At some point, she even removed the substrate that she used to close up her back door. She's there right now, half inside and half outside the burrow. I offered her another mealworm and she didn't take it. From everything I've read, I believe she's in pre-molt and I should just be patient. Her abdomen is still nice and plump, but her behavior is throwing me off because some days she's more active like today. Reopening her backdoor also threw me off.

I'm going to post some photos taken of her during the last couple days and I would love to hear feedback from others who have had G. Pulchras or experience with slow-growing spiders. I really love my spider and am doing everything I can to care for her according to best practices because I want her to be healthy and feel safe. I hope to spend many years with her and could really use some reassurance that she is in pre-molt. Or, if some don't think she is in pre-molt, some advice on what to do would be appreciated. I know I have to be patient with a T like her, but it's my first time going through this, so my confidence isn't high.

Thank-you in advance to anyone who replies.

Your sling is telling you that it's full. You fed it way too much, way too often, and now it's not hungry. It's a common mistake by new T owners, specifically with slower growing genus like Grammostola and Aphonopelma. I've got 3 G. pulchra of various sizes, and the one around the size of yours is on day 506 of this current molt cycle - they take a long time between molts. If you feed them a ton of food early on in the molt cycle, then they'll fill up and won't want/need to eat until after the next molt. Mine still eats regularly because I feed it a small-medium cricket around every 2-3 WEEKS, not 2 large crickets every 2-3 days...

For now, there's no need to keep offering food, it's a waste of time. Just make sure there's a full water dish in the enclosure at all times and maybe try offering a small cricket in a few weeks. If it doesn't eat, wait a few more weeks and try again. If it doesn't eat, it doesn't mean anything other than it's not hungry and you need wait longer. Just enjoy observing it do spider things and it'll molt eventually. Then you can start over with a more reasonable feeding schedule. 👍

its fat and either full or has been stuffed into a long premolt just wait a week and try feeding pre killed again. then rinse/repeat until it actually molts also be carefull about exposing it to sunlight from an open window you might cook it. good luck

No one would judge you if you added another tarantula to your collection, to help you pass the time between molts 😂

Thanks to everyone for their input and advice. I’ll be sure to feed her more conservatively in the future. She’s a lovely little spider and I enjoy watching her be a spider - not just feeding time, which is over very quickly. I honestly thought juveniles had to be fed 1-2 times per week because that is what I’ve read and heard just about everywhere. She was already quite plump when I got her.

I’m getting a GBB sling in a week, so that will be fun. While Noche (my G. Pulchra) is spending time in her burrow, I can watch Día (my GBB) web up her enclosure.

good to hear that, be sure to be more conservative with the feedings from now on.
the abdomen is a clear visual indicator you can use to determine your feeding schedule

I have a G. pulchra of similar size, and he behaved very similarly before his last molt. These guys are little piggies and will eat and eat and eat until they stop. Mine is fat right now too but would happily still eat if I gave him something, so I'm not offering.

The premolt period is really hard to discern, and I went through this last year with Luca. He burrowed away and stopped eating for about 5 months, came back up and had a couple of meals over another month or so, and then burrowed away again. His abdomen was plump for many, many months before darkening about a week or two before the molt happened. I know individuals don't always behave the same way, but that was my experience with him. Similarly, my B. hamorii had a plump, shiny abdomen and refused food for about 6 months before she molted. Hold off on feeding, but don't be surprised if you're waiting many more months for him to show some of the more obvious signs that a molt is imminent.

That T is THICC, chill with the feedings for a bit. Good luck with the GBB, you will enjoy it. This is one of my favorite species!

Do not "overfeed" or she will fast for ages... even more than a year.

Excavating wise, that's because of loose substratre or just because she is looking for a more humid and cooler spot to chil on. From time to time give to the substrate a slight mist, just enough to not keep it overly dry, or she will enclose in her burrow, specially around her burrow. Not too much, just a bit.

Mine changed completely after ditching the coco fiber and start using good topsoil, peat and clay based one. I'd give it a try 😎👌🏼

Also do not feed her bases on schedules, it's a much better option to do it based on her abdomen's size and behaviour. You will know when she's hungry 🤣🤣🤣

This is a typical pose when she is looking for food.

Fat tarantulas don't need food!!

Stop obsessing over feeding it....it will begin eating after it's next molt....and that could be a long while because it was fattened so quickly.

Hey there! How’s Luca doing? Your observations have been helpful to me because you are a little further along with Luca than I am with Noche, but they’re about the same size, so it gives me some idea of what to expect.

For those suggesting soil, I have some repti-soil or whatever the Exottera soil name is for when I rehouse her or have to clean her enclosure, but for now I’m going to stick with the coco husk and a really simple setup. She seems to like a clean and uncluttered space. I put some dry leaves down on the substrate just to make it more…dynamic a few weeks ago and she was not happy. Started climbing the roof again until I removed them. I’ll try again when she’s bigger. I want to find a nice rock to add for now, and maybe a small succulent in a few months.

I’ve been using a trick I learned from Tom Moran and am wetting a corner every few days until the moisture reaches a couple inches up the substrate. That way she can burrow to a level that has the amount of moisture and humidity she likes.

Here’s a pic of her peeking out her back door. She loves to relax like this, half in and half out.

What at @Dorifto said about a bit of moisture is good advice. Its not rainfall type spritzing. Its light, and not every week. Its just to keep some kind of moisture.

a wet corner tom moran style isnt bad. But it can help to have a part of the burrow slightly moist. If the tunnel is long, you can choose where to inject a bit of water.
