Baby Turtle in a 10 gal tank?

if it is still a baby a 10 gallon tank should be fine for awhile and many animals will only grow as big as their enclosure allows. we found a baby red ear slider when it was aproximately the size of a fifty cent coin piece and over about a four to five year period it grew to the size of abouta playing card, at this time that is the closest thing that comes to mind to give you a comparision. i am not familiar with the type of turtle you mentioned but lots of turtles like to have and area to get out of the water on, petco and petsmart have special turtle docs that you an buy for like 10 to 15 bucks depending on the size. and just try to give it a good variety of food that it eats. also if your tank dose not have a filter, it would be a good idea to invest in one, it is not necessary to have a filter but it helps tremendously, turtle water can get very dirty,stinky and just plain nasty very quickly and a filter helps out alot. recently i had a baby red ear slider that lived in one of those small i think 1.5 to 2 gallon goldfish or beta tanks and he/she did just fine, so i believe your 10 gallon tank is plenty big. hope i was able to help, goodluck with your turtle freind. mine is little turtly dude
