hay,

that would be okay for two small turtles, really depends what turtles your intrested in?
the most common turtles people buy are yellow bellied sliders from fish shops and garden centers, but sliders get BIG males are small and get between 8-10 inchs and females get av. 13 inch. that would last two 50p sizes sliders untill there both bout 3 inchs, and they like deep water, but like i said depends on what turtle. i have 4 chiense striped necked babys (bout an inch big each) in a 2ft by one foot tank, but will last them to about two and a half inchs. i can send some pics of my setups if you like? i have 3 diffrent tanks, 8 turtles and 3 diffrent species, and my friend has about 400 turtles!
however any turt needs a uv and a basking spot and a dock
but that tank is excellent for baba turtles!

oh and turtle BITE HARD! lol our fingers look like prawns! yummy! and they are messy, i clean out mine once a week, and you need a strong filter! they do big poo's...
