Fuzz on the neck

Question
I have 4  red eared sliders I got from Panama City Beach, FL.  I know 1 has the minor fungus on its neck becuase it's VERY noticable.  Do I need to treat all 4 turtles with the sulfa dip?  

And another question.  I have a 10 gallon tank, is that big enough to house all 4 turtles???  

Thanks.

Answer
A 10 gallon tank is the recommended size for one very young Red-ear. The rule of thumb is about 10 gallons of water per inch of shell length.

Especially when they are crowded, if you treat one, you should treat the rest.

If the sulfa dip does not help in a week, go to a more aggressive treatment applying Betadine Solution to the fungi and letting it dry before you return it to the tank.
