Wow, ok turtles get HUGE. I'm going to asume that these are a type of slider. Males get to be 8-9 inches and females get to be 12 inches, so yes they will get MUCH bigger. It's illegal to sell turtles under 4 inches. You'll be fine, just don't tell a cop. I did the same thing not knowing the law. They should have 10 gallons of water per square inch of their shell. They're 1 inch so they EACH need 10 gallons of water. Honey, they're aquatic turtles, NO they can't have too much. This is why they have little flippers to swim with. Yes they can make you sick if you handle them. They might carry Salmonilla, but just be sure to wash your hands throroughly and you'll have no problems. Since I'm here, I'll give you some more advice on the care of turtles.They NEED both UVB and UVA lighting. UVB prevents metabolic bone dissease, synthesizes calcium, and produces and synthesizes vitamin D3. Their water needs to be between 75 and 85 degreese F and they need to have a basking spot completely out of water that is between 85 and 95 degreese.You need to feed them a steady diet of pelet food (T.Rex and ZooMed's make awesome turtle food), and add some snails, small crickets, and meal worms to either diet for added protein. When they get bigger (about 4 inches) then you can feed them feeder fish (goldfish, rosey reds, platys, other minnows) but not yet because your turtle's too small.Be sure to have a good filter made for turtles or a fish filter said to do 2x more than your tank size. Change the filter regularly and clean the tank once a week. This also helps keep away diseases.You can add a plant called Anacharis to the tank too which helps keep it clean. It eats their poo and turtles have a LOT of poo.Good luck with your little guys and if you have any more questions just ask!
