Right, 3 days ago i put 2 odessa barbs in my 15G and i believe that they spawned for me

So i knew i wouldnt see anything for the first 24 hours after taking the parents out because the eggs wouldnt have hatched, i waited for a day, the eggs should have hatched but i still decided that i wouldnt be able to see the fry, today is the day the fry should have become free swimming and on the back glass of the tank i can see one little grey line and 2 little white dots on either side of its head, is this one of my odessa barb fry?
Thanks
