Great,my computer is acting weird again.
Man do I dislike my computer
Looks like you been given Red Ear Slider turtles.
Now here's for the Uh-Oh.
I have 2 of them.
I really hope you can spend money in an exceptional filter,your going to need it...hehe.
Lets see,mine are almost adult,hard to tell the gender at that age by the way.
The teeny tiny turtles you have there.
These amazing animals can grow as large as a dinner plate.
Not to mention they need an heater& a basking light& basking spot.
Aquarium wise,three adult turtles,your looking at a 200gallon or so with an even greater filter.
They grow fast.
Your turtles at the moment will be more carnivorus as opposed to mine which prefer more plant matter since they are older.
You'll need a varied diet,don't just feed the pellets!
You can expect to change water weekly.
They're tiny yet,so you can maybe go two weeks.
Calcium is great as well.
Remember these guys can get shell rot,it's not pretty.
You have a lot of work cut out for you.
This is also a species that's very long lived.
Oh you can get little blocks in the shape of a turtle to put in the tank.Also cuttlebone (yeah like for birds) that'll help get calcium in the little guys.
Turtle lagoons are cruel.
Not to sound mean,but you really should research any living creature before bringing it home.
No pet wants to be passed around from home to home,it's traumatic.
