Keep Getting Error About Reaction Time

I need some help, I have confidence that the code is okay- but I keep receving the error "If the frog's reaction time is greater than the fly's reaction time, the frog can't get the fly."

Am I missing something?

Frog.cs 
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;
        public readonly int ReactionTime;

        public Frog(int tongueLength, int reactionTime)
        {
            TongueLength = tongueLength;
            ReactionTime = reactionTime;
        }

        public bool EatFly(int distanceToFly)
        {
            return TongueLength >= distanceToFly;
        }

        public bool EatFly(int distanceToFly, int flyReactionTime)
        {
            if(TongueLength >= distanceToFly && ReactionTime <= flyReactionTime);
            {
                return true;
            }
        }
    }
}

There's a stray semicolon after the "if" statement that prevents it from working, and the function still needs to return a value when the condition is not true.

When I remove the ; at the end of the if statement I get

Frog.cs(19,21): error CS0161: `Treehouse.CodeChallenges.Frog.EatFly(int, int)': not all code paths return a value
Compilation failed: 1 error(s), 0 warnings

I'm still a little confused; do I omit the semicolon? And from what you said:

and the function still needs to return a value when the condition is not true.

Should I create an else statement? :( I appreciate the help!

You don't need an "else" since the function will have already returned otherwise.
But you do need a "return false;" at the end to fulfill the requirement of returning a bool.

Oh! Got it! Now I know what needs some practice. Thank you! I marked this as the best answer.
