For example, the death of the only fish in an 11-litre (3 US gal; 2 imp gal) tank causes dramatic changes in the system, while the death of that same fish in a 400-litre (110 US gal; 88 imp gal) tank with many other fish in it represents only a minor change. For this reason, hobbyists often favor larger tanks, as they require less attention.
Day temperature should be maintained at 77–86 °F (25–30 °C). Night temperature should be maintained at 70–75 °F (21–24 °C). A basking light should be installed in the tank and a temperature of 90–95 °F (32–35 °C) must be maintained. Natural light is best for reptiles, but a UVB light can be installed in the terrarium. A 5.0 ...
The Indian rat snake (Ptyas mucosa) is also very large with maximum sizes of up to 3.7 m (12 ft), making it the second-largest species in the genus Ptyas. [ 61 ] [ 62 ] The Tiger rat snake ( Spilotes pullatus ), which usually grows to about 3 m (10 ft), has been reported to reach up to 4.2 m (14 ft), ranking it among the largest colubrids . [ 63 ]
Epoxy-coated plywood vivariums retain heat better than glass or plastic enclosures and are able to withstand high degrees of humidity. They may be cubical, spherical, cuboidal, or other shapes. The choice of materials depends on the desired size and weight of the entire ensemble, resistance to high humidity, the cost and the desired quality.
Hermit crabs should be kept in glass tanks of an appropriate size in order to maintain the humidity and temperature needed. At least 10 gallons of tank space should be provided per hermit crab. [45] Overcrowding a tank can result in aggressiveness and cannibalism between crabs. [49]
However, specimens exceeding 6.1 m (20 ft) in length and 1,000 kg (2,200 lb) in weight have been recorded. It is the largest predator in Africa, and may be considered the second-largest extant reptile in the world, after the saltwater crocodile (Crocodylus porosus). Size is sexually dimorphic, with females usually about 30% smaller than males ...
The largest living species of turtle (and fourth-largest reptile) is the leatherback turtle, which can reach over 2.7 m (8 ft 10 in) in length and weigh over 500 kg (1,100 lb). [9] The largest known turtle was Archelon ischyros , a Late Cretaceous sea turtle up to 4.5 m (15 ft) long, 5.25 m (17 ft) wide between the tips of the front flippers ...
[107] [108] Starting in 2015, the Cincinnati Zoo built a US$73 million exhibit to house three adult hippos, featuring a 250,000 L (55,000 imp gal; 66,000 US gal) tank. Modern hippo enclosures also have a complex filtration system for the animal's waste, an underwater viewing area for the visitors, and glass that may be up to 9 cm (3.5 in) thick ...
