Unexpected Fry

Hi, I've been experimenting with live foods in my ember tetra tank because I wanted to try my hand at trying to hatch eggs from Aphyosemion australe (Lyretail killifish) at some point in the future and they need live foods. Now I'm seeing one ember tetra fry swimming near the bottom, the adults are all using the middle almost exclusively.

It is a 10 gallon tank and I'm worried the fry will not get enough food when the adults get food, especially because I think this little guy needs even smaller foods than what the adults eat. I have some Hikari first bites, because of wanting to try the killifish. I will put some in some water and pipette it down there to him.

I have a fry tank that was supposed to be for the eggs, so I could take him out and put him in there and try with the microworms I already have a culture of. I am very worried about harming him when I transfer him though, he is so small!
Or I could keep him in the 10 gallon. What is the best way to do this?

I tried to take a picture of him, but its' almost impossible to see him, But he's in the middle of the picture, he's mostly eyes.

 

Tried to catch him to put him in the fry tank, so I could feed him microworms more easily. But he's wayyyy too fast for me. So he might have to stay in the 10G anyways, unless I manage tomorrow.

 

I couldn't catch him with the net but I used my gravel cleaning hose, took the strainer head off and vacuumed him up along with the tank water that I wanted to put in the fry tank anyways. That worked perfectly and I'm quite sure the net would have had much more chance of hurting him. I will put some of my duckwead and mini water lettuce in his tank, that should help him too.

 

Retired Viking: I read that ember tetra sometimes will eat their fry so I didn't want to take the chance. Having an area where they can hide might make their survival rate much better though. I don't have experience with that.

 

The mini water lettuce stays on the surface but it does have pretty long roots up to about 2 or 3 inches. but I can keep it under control more easily. It It grows by sending trailers out over the surface on which new clusters of mini water lettuce grow.

 

I found a second fry in the tank and moved it to the fry tank, so now I have two! There is a bit of size difference but not too bad.
