If it has made it this far chances are very good that it will make it to adulthood . You need to crush up some flake food as small as you can and watch and make sure it gets some . You can feed it a few times a day . Just a little each time until it gets bigger . Just make sure you stay on top of your weekly water changes until you can stop the multiple feedings .
We are meant to be the stewards of the Earth and her creatures....not the masters.
