It would help to know what type of turtles you have but I'll assume they're red-ear sliders because they're the most commonly sold babies. So you know, they will grow to 4-6 inches- if they don't then they aren't healthy. They should enough water in the tank so that they can completely submerge themselves but they also need a dry area to bask. As they get bigger and stronger they'll need more water so that they can swim around. Consider getting the largest tank that you can afford, as turtles need about 10 gallons of water per inch of their shell's length. In addition they need a UVA/UVB lamp as well as a basking lamp. Also, make sure you clean their tank once a week. Dirty water will make them sick. You will most likely not get sick from handling them, but you should wash your hands after you do so. Don't pick them up right away after you wash your hands though because the soap residue on your hands will make them sick.
