The Fry is doing well?

A few weeks ago my fish had a few babies. I have saved 2. This is the longest the fry has stayed alive for me. I have newborn food for them... but as the weeks have gone by I have realized one of them is thriving! The other one isn't as big and doesn't have as much color...

Am I doing something wrong?

It's not at all unusual for fish to mature at different rates. The larger fish usually get most of the food and grow even larger as a result. Fry are exceptionally sensitive to toxins in the water so it's especially important to give them a healthy environment. Abundant floating plants will also increase their survival rate.

In the wild, only a very small percentage of fry make it to adulthood.

Ahh, yea... didn't think about the different growing rates. It's just real noticeable and I was worried...
He seems to be doing good like the other so I guess thats good!

thanks for the reply!
