   ifstream _wildeq;
    _wildeq.open("wildlifeequations.txt");
    if(!_wildeq.is_open());
    cout<<"Fail"<<endl;

    string read;
if(_wildeq.is_open())
{
while(_wildeq.good())
getline(_wldlifes, read);
cout<<read<<endl;


}

Did you make sure the file "wildlifeequations.txt" existed?

If the file exists and you can't open it then it is probably a good bet it is in the wrong directory and/or the path to it needs to be setup.

Also why test whether the file is open twice when once should be enough.

That's the issue I'm having. It is in the correct directory.
The only reason I have it to where it checks if its open twice is due to instructions.

What issue?

It is in the correct directory.

Doesn't sound like it to me. That is, if your program runs.

The only reason I have it to where it checks if its open twice is due to instructions.
Try it as below and ignore the bad instructions for a while.

Try the samples here as a model.

It might be a good idea if you post a short but complete piece of runnable code with sample text file of a couple of lines.

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    ifstream _wildeq;
    _wildeq.open("data.txt");
    if(!_wildeq.is_open())
        cout << "Fail" << endl;
    else
    {
        string read;
        
        while(_wildeq.good() )
        {
            getline(_wildeq, read);
            cout << read;
        }
    }
    
    return 0;
}
