Lone Survivor

In my community tank I spotted a single lone fry. What should I do to save him? I know fish don't just give birth to one or two so the others must've gotten eaten.

Also please help me determine what species it is. It has reflective blue eyes. Apart from that its still in its tadpole-like form.
'In my tank I have rummynose tetra
snakeskin barbs
a pair of bosemani rainbow
otocinclus
a single male ram (so it can't be from him)
a single molly (so it can't be from her)

More info:
tank pH is around pH 7 before CO2 comes on. pH drops to around 6.2 before CO2 goes off.

 

Its probably a molly if its a her. They can store sperm for 6+ months

 

Ive had her for 1 year though

I looked up molly fry. Way too small to be a molly fry. Could it be bosemani? I read they don't often eat their fry.

 

Could you post a photo ?

Also to save it I would get a breeder net and put it there

 

Yes I have caught it with a net to prevent it from being eaten, but now I can't seem to find it in the net...
Here's a picture:

 

Look, for all I know that could be a mosqi some bug with an easier name to spell. However, I have seen that before and of all of your fish the only one that I have watched videos on is the rummy-nose. (You know I'm right.)

 

My guess is that it’s a rummy nose . Because of the size

 

I did a quick search and bosemani rainbowfish fry have blue eyes. That fits my description. Although it is very small.
Unfortunately it's nowhere to be seen anymore. Guess I'll just keep adding egg yolk into the net for a week and see if anything pops up

so cute ❤

 

The Rainbowfish lay tiny eggs and have tiny fry, and are far more likely to have spawned than the Rummynose. The water has to be extremely soft and acid for Rummynose to spawn, and from the info given I'd guess that OP's water is not that soft.

Good news, I found 2 more fry. Will be getting a proper breeding net today for them. Question though, There's not convenient place to mount the breeding net in the tank they're currently in without shading plants. Is it safe to quickly transfer fry in the net to another tank?

My water is actually very very soft, but I agree with you chromedome52. Female bosemani has a big belly right now
The thing is though, I read their eggs take a week to hatch. So if I'm already seeing swimming fry, that means she's been actively laying eggs for a whole week now? Is that possible?
