So, I've had this little hoggy for about 7 months now. She's been a rather finicky eater, only gaining about 20 grams whereas her brother has skyrocketed to 90g. She hasn't eaten in 6-7 weeks now. I'm starting to get a bit worried. She hasn't lost more than a gram, but she's still very small. I'll give y'all some info about her and what I've tried so far...

She's been kept in identical housing as her sib, so I don't think it's husbandry related. Both are in 6qt tubs with aspen and 1 hide, temps are good, provided by belly heat and stable, humidity is kept as low as I can get it. When I first got them, they'd only eat in a darkened container, so that's how I've been doing it since. They're on a 4 day feeding schedule. Handling is at an absolute minimum, only to clean, fill water and make sure she's alive.

For the first 4 weeks or so, I offered as I usually do. After missing around 7 feedings, I decided I needed to change things to get her eating again. I first tried moving her to a smaller deli cup, offering the same f/t pink as usual. No luck with that. Then I tried a live pink overnight, but she seemed very scared of it and wouldn't go near it. I've tried scenting with tuna juice, also a bust. Last night I scented with anole and she FREAKED OUT. Hissing and rattling, feinting at me. It was crazy. I don't want to overwhelm her with all of these new things, but I'm at a loss.

Here's some things I've read, but have yet to try:
Take away water for a week, then offer pink soaking wet, hoping thirst will encourage her.
Offering a piece of boiled egg white.
Dipping pink in egg yolk.

Should I just not worry about it, wait til she decides to eat? It could be weather-related, one of my balls has been off feed for the same amount of time (not worried about him, he's got 1kg on her). I really don't want to assist as I've read about the damage you can inflict on them. I would appreciate any suggestions.
