UV веслоногам

Как вы думаете, какую лампочку поставить веслоногам Polypedates?

Если исходить из вот этого:

The group was initially housed in a 40 x 40 x 40 cm glass vivarium with a mesh panel in the lid. As this frog is an arboreal rainforest species it is likely to be exposed to UV-B radiation in day time retreat sites. UV-B radiation is important for the synthesis of vitamin D3 which plays an important role in calcium metabolism, muscle development, organ formation, muscle contraction and immune and nervous system function (Whitaker & Wright, 2001). Captive P. leucomystax develop metabolic bone disease when UV-B radiation is not provided, even when prey items were dusted with vitamin D3 containing supplements (Tapley B, pers. obs.). UV-B provision was therefore considered important for the captive maintenance of P. otilophus. This was provided by mounting a UV-B emitting lamp (1150 mm T5-HO UV-B) uorescent tube (D3+ 12%UV-B Reptile Lamp, Arcadia Products plc, Redhill, UK) above the mesh of the vivarium top. UV Index (UVI) readings were taken on a monthly basis with a Solarmeter 6.5 UV Index Meter, UVI gradients were measured through the mesh lid and ranged from a UVI of 0 – 4.0 at the level of the frogs’ dorsal surfaces. The oor of the vivarium had a built-in aquatic area which measured 40 x 12 cm and was lled with aged tap water to a depth of 3 cm. Compacted organic peat free compost was used as a substrate. A single bird’s-nest fern (Asplenium antiquum) provided a resting site for the juvenile frogs. Branches were angled from the water into the back top corners of the vivarium and it was on these branches that the highest UVI reading (UVI 4) was measured. The frogs rapidly outgrew their enclosure.
