Regular additions of fresh water is crucial for the tadpoles. If you have regular rainfalls, you can let the tank sit under a tree or shrub in the garden and allow the rainfalls to refresh your tank. You just need to watch the level to make sure it doesn't overflow and wash away some of your tadpoles.adpoles have gills so they need really clean water just like your aquarium fish. If you plan to get some tadpoles, you'll need to get your water ready before you bring the tadpoles home. The best practice is to use rain water but there will be some who can't use rain water.
It may look like a dog, but the spotted hyena is more closely related to cats, civets, and genets. Also called the laughing hyena, the spotted hyena is a strong, capable hunter. It is the largest member of the hyena family (other members are the striped hyena, brown hyena, and aardwolf).
Males in most hyena species are larger than females, though the spotted hyena is exceptional, as it is the female of the species that outweighs and dominates the male. Also, unlike other hyenas, the female spotted hyena's external genitalia closely resembles that of the male.yenas are primarily nocturnal animals, but sometimes venture from their lairs in the early-morning hours. With the exception of the highly social spotted hyena, hyenas are generally not gregarious animals, though they may live in family groups and congregate at kills.
