Why is my Hermann's tortoise not eating?
A Hermann's tortoise that goes off its food is most often reacting to its setup, a basking spot that's too cool, a UVB tube that's aged out, or a natural seasonal wind-down before brumation. Dehydration and the stress of a new home are the other common culprits, and a warm soak is usually the first thing to try.
Check the basking spot and UVB
Hermann's tortoises need a basking spot of 32–35°C (90–95°F) to warm up enough to digest and feed, if it's drifted cool, appetite fades. Just as important is UVB: a fluorescent UVB tube stops producing useful output long before it stops glowing, usually within 6–12 months, so an aged-out tube leaves a tortoise unable to process its food properly even while the light still looks fine. Measure basking heat with a digital probe and note when the UVB was last changed.
Is it a pre-brumation wind-down?
As days shorten and temperatures drop in autumn, a healthy Hermann's naturally slows and eats less in the weeks before brumation. This is normal seasonal behaviour if the tortoise is otherwise well and holding weight, but only a healthy, well-hydrated tortoise should be allowed to brumate, so it's worth distinguishing a natural wind-down from illness.
Dehydration and warm soaks
A dehydrated tortoise often won't eat. Soak it in shallow, lukewarm water up to the lower shell for 15–20 minutes a few times a week, tortoises drink and rehydrate through soaking, and it frequently perks up appetite within a day or two. Fresh water should always be available, and leafy weeds and greens carry useful moisture too.
A new home or recent change
A newly-acquired or newly-moved tortoise commonly refuses food for a week or two while it settles into unfamiliar surroundings. Keep the setup stable, get temperatures and UVB right from the start, minimise handling, and give it time. Through any refusal, weigh regularly, a steady weight is reassuring, while ongoing loss is the real warning sign.
When to see a vet
See an exotics vet if refusal persists outside the pre-brumation season, if weight is dropping, or if it comes with lethargy, sunken or swollen eyes, a runny nose, wheezing or a foamy mouth, and before letting any tortoise brumate that has lost condition or hasn't been eating well.
One reading rarely tells the story. What matters is whether it's an isolated blip or part of a trend, so look at recent weight, feeding intervals, shedding, temperature and behaviour together.
baskr keeps those records in one place and watches the pattern for you, so you can see whether something has genuinely changed with your hermann's tortoise, before it becomes a problem.

Why did my Hermann's tortoise suddenly stop eating?+
Check basking temperature and UVB age first, a cool basking spot or an aged-out UVB tube are the usual causes. Then consider whether it's the pre-brumation season, whether the tortoise is dehydrated, or whether it's newly settled.
Is it normal for a Hermann's tortoise to stop eating in autumn?+
Yes. A healthy Hermann's naturally winds down and eats less in the weeks before brumation as days shorten. It's normal if the tortoise is otherwise well and holding weight, but only healthy, hydrated tortoises should brumate.
Will a warm soak help my tortoise start eating?+
Often, yes. Soaking in shallow lukewarm water for 15–20 minutes a few times a week rehydrates the tortoise, and a dehydrated tortoise that's been off its food frequently regains its appetite within a day or two.
How long can a Hermann's tortoise go without eating?+
A healthy adult can go weeks, especially heading into brumation. But refusal paired with weight loss, lethargy or a runny nose is not seasonal and needs a vet, track weight rather than counting missed meals.
