Sailfin Dragon

Hydrosaurus pustulatus

Part of this is not on the page we cite. We opened it on 10 Aug 2026 and some of the degrees above are not stated there. The values above may still be right, but we cannot show you where they came from, and nobody here has checked them against a second source. Anything about a sick animal goes to a qualified exotic vet, not to a page. bion.com.ua

Day: a real gradient, 35°C warm against 27–32°C cool, so the animal chooses. Night: 21–27°C.

Why

Same scale on every sheet here, so two species compare by eye.

The sheet statesWe use simple fluorescent lamps for lighting. UV lamps are obligatory.

Diet
Diet for juveniles consists of herbs (dandelion, nettle, hemp, clover, arugula, coltsfoot, flowers of acacia, roses, etc.) and insects (crickets, turkestan cockroaches and locusts); We offer plant food every day and insects – every other day; adults: fruit, berries and vegetables (apples, apricots, peaches, kiwi, bananas, grapes, persimmon, blueberries, raspberries, currant, radish)

Drawn from the stated numbers. Only what the sheet states is drawn inside.

Why

The rectangle carries the exact width-to-height ratio of the figures above it, and the ruler under it places that width on the 0–250 cm scale every sheet here shares, so two species still compare at a glance. Nothing is added that the sheet does not name: a lamp drawn on a sheet that never mentions one would be invented equipment. What the sheet leaves out is listed rather than left blank, because an empty tank reads as « none needed ».

The sheet statesIt is recommended space of 200x80x150 cm per one adult individual; We keep juveniles at 120x50x70 cm (47x20x28 in) enclosures

This sheet states a range to hold. Your local climate decides how much work holding it is. Pick the nearest city: nothing is sent anywhere, the choice stays in this browser.

Common questions

How big does it get and what do I need?

Around 1 metre with the tail, and it needs a tall enclosure with a large water area. One of our most demanding lizards.

Is it tame?

Usually skittish. Many injure their snouts running into glass, so visual barriers and cover are essential.

How much does it cost to run?

High. Big enclosure, strong lighting, frequent water changes and a mixed insect and plant diet.

Does it bite?

It can, and it also whips with the tail, but running away is always its first choice.

This sheet states 5 of 7 of the fields this product runs on. What is missing turns something off: day/night engine and awake count on the globe, the diet section. We show the gap rather than fill it with a plausible number.

UVB is measured but does not count: it is absent from 421 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
