Nature can always find a way, I'm truely surprised that the little guy made it. When the Diamond Tetra spawn they go up into the floating plants to deposit their eggs ... and all five of my angels sit below completely vertical looking up for snacks. You would be suprised how far they can squeeze their very tall bodies into the tangle of the Water Sprite to get at them.
On top of that, I do not put anything in special to feed fry as I'm not trying to raise them.
S/he would still be a single gulp snack for the Angels, but he has made it this long (and through a few water changes) so I would like to think he'll make it all the way. And thus the Diamond Tetra school gets a little larger... hopefully it turns out to be female, I have plenty of males.
The more I think of it though, the more I feel that it will be at greater risk at about neon tetra size. Large enough to venture out into the tank, but stil small enough to be killed by the angels.
I would move the fry to another tank if that is possible. Angelfish are predatory, and if they see it they will get it.
If there is sufficient secure cover like thick plants, wood, etc. in a tank, and fish spawn, some fry will often survive. If the tank is established, there will be microscopic food within the plants and wood, and sufficient for a couple fry. Provided there are no predators in the tank, that will readily eat any smaller fish, a couple fry may well make it to maturity. I have found that the fish species itself rarely bothers them once they are out and about, even though small. I've had this with Emperor Tetra (currently 12 adult fish in my 90, all hatched in this tank from the parents that I gave away), various pencilfish, diamond tetra, kerri tetra, corys. All with no intervention from me. But again, there were no real predators in the tank, only the parent fish and similar, and at about 1/2 inch the fry seem to be ignored.
When I see fry at this stage, I sprinkle in some finely-ground flake food when I feed the normal flake, as the fish can eat this. Dry leaves are excellent if you want fry to survive in the future; just keep some dry leaves (oak, beech, almond) in the tank. My Farlowella fry are growing nicely on these, on their own of course in the 10g. They are very slow growing, and I had to remove them from the main tank when they hatched because the other fish were easily grabbing them up.
