Insects should be vitamin supplemented once every other day for the first 12 months and twice a week thereafter. Water should be lightly sprayed into the vivarium once or twice a day to keep humidity levels up.
The next lizard is the green iguana. The green iguanas scientific name is Iguana iguana. It originates in Central and South America. Both males and females will reach lengths between 60"/150 cm and 72"/180 cm. Adult males will have a large dewlap and a larger crest than females. They can become tame if a lot of time is spent with them, they can be allowed to wander the house under light supervision. Males are very territorial and should never be kept together because fighting will occur and as a result the death of the weaker one is likely. One or two hatchling/ juvenile Iguanas must have a vivarium at least 36"/90 cm long, 18"/45 cm deep and 18"/45 cm high, but an iguana will out grow this. Adult iguanas will need a huge enclosure and for one or two adult Iguanas the vivarium needs to be at least 72"/180 cm long, 36"/90 cm deep and 36"/90 cm high. A wood based substrate such as wood chips should be used. A spotlight above one or two branches will provide your Iguana with a suitable basking site. Daytime temperatures should vary from 78F/26°C in the cool end to 90F/32°C in the basking area. At night, temperatures can drop to a low of 72F/22°C, because Iguanas require a quite high nighttime temperature, a heat mat may need to be installed. A UV bulb that gives out about 5% UVB and 30% UVB should be installed at the top of the vivarium. Iguanas are arboreal and so should be provided with plenty of branches to climb on, plenty of fake plants should be used to provide cover for your Iguana. Also a big, quite deep bowl of water should be kept on the floor of the vivarium because they love water and like to lay in it, so the bowl should be larger enough for your iguana to lay in, the water needs to be changed every day or two and immediately after an Iguana has defecated in it.
