Longer than only 47% of all species in Lamprophiidae anyone has measured.
The bar is the rank itself: its length is the share of the family this animal exceeds. The chart below is the family’s real spread, on a logarithmic scale because body length here runs from 235 to 1,750 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

"actively searching for reptiles and amphibians" and "has previously been documented to eat Kassina senegalensis Dumeril and Bibron, 1841 and young Pyxicephalus edulis Peters, 1854 (Pienaar, 1966) and Phrynobatrachus spp." (Kyle et al. 2021), frogs only (Wilkey and Terrell 2017, Pietersen et al. 2021), anurans (Marais 2022)
"actively searching for reptiles and amphibians" (Kyle et al. 2021), also Wilkey and Terrell 2017
These snake were recorded hunting puddle frogs in the muddy elephant footprint in the late afternoon (Broadley and Blaylock 2013), Found during the day and evening,foraging for frogs in marginal vegetation around still water (Branch 1998), "All specimens were found between 20:00–24:00 h, despite extensive searches during dusk and early evening. Except for Pienaar’s two specimens found during the day (Fitzsimons, 1964), all specimens were found after sunset, suggesting they are largely nocturnal." (Kyle et al. 2021), nocturnal.. hunts in the late afternoon or early evening (Wilkey and Terrell 2017), late afternoon and evening (Pietersen et al. 2021), crepuscular and nocturnal (Marais 2022)
"All were found within two metres of the edge of temporary pans, in grass and sedges on the wet mud fringe surrounding the water, presumably while they were foraging" (Kyle et al. 2021), in or near water" (Marais 2022)

Keeping one
2 ft 2 in × 13 in × 19.5 in(66 × 33 × 50 cm)
Minimum length × width × height, for one animal. Bigger is always better.
The standard sizes snakes as a fraction of total length: 1 × 0.5 × 0.75.
Mindestanforderungen an die Haltung von Reptilien (Sachverständigengutachten), German Federal Ministry for Nutrition, Agriculture and Forestry, Animal Welfare Division, 10 January 1997. The standard states these floor areas are recommendations rather than binding limits.
From this animal’s own total length of 2 ft 2 in (660 mm), at 1 × 0.5 × 0.75 times it, following the German federal welfare standard — how this is worked out.
No preferred body temperature has been recorded for Floodplain Water Snake. Rather than repeat a number from a care sheet, this page leaves it out.
Feeding
A prey item should be between the same width as the widest part of the snake's body and about 1.5 times that width.
Widely used across snake husbandry references. An alternative formulation gives prey at 10-15% of the snake's body mass. This is established practice, not a measurement.
8kJ per day
Worked out for an animal of 62 g, the heaviest recorded for Floodplain Water Snake — so it is the top of the range, not a figure for a particular animal. Weigh yours and the number will be lower.
An upper estimate, not a feeding target, and not veterinary advice. The equation covers only what an animal burns staying alive, so a growing, gravid or recovering animal needs more — and it was measured on wild animals, which move far more than one in an enclosure. Body condition and a vet who knows the species are what a feeding decision should rest on. Where this comes from.
What nobody knows
These are not gaps in our research. No scientific dataset records them for this species — and saying so is information you cannot get from a reference that simply leaves a field out.
