Red-eared slider turtles usually can only breed successfully if they have hibernated before, and turtles kept in tanks rarely hibernate. There is a miniscual chance your turtles will breed if they have not hibernated.
Any normal filter will work. Chacha on!!
All turtles need to have mated in order to lay eggs, unlike birds who will lay infertile eggs, turtles won't.
No they do not breathe under water. They have lungs. Aquatic turtles such as the red - eared slider can hold their breath for 3 - 4 hours.
around 80 degrees.
No need to care for it. There are already enough red eared sliders in the world.
Yes, but only as a treat. Turtles need a varied diet, and Red Eared Sliders move to a more plant based diet as they grow. Giving them too much protein can cause odd shell growth, and eventual deformation.
Fresh water, with a strong filter. Change water once every month.
no,You need both uva and uvb light
yes
Yes, as long as it is large enough to accommodate the turtles. While a hatchling can live in a 10 gallon aquarium, it will soon need a 100 gallon aquarium as these turtles get up to 12" in shell length.
Aquatic turtles need to live in water. How deep depends on the species. Turtles like painted turtles or slider turtles need water to be as deep as possible. Turtles like musk and snapping turtles need shallower water. They have to have land too, a turtle need to be able to completely dry off when ever they want to. Tortoises or box turtles need a shallow, easy to climb in, dish that is big enough for then to fit in so they can sit in it and drink when ever they want.
