Super Small Fry ? How Small Can Guppy Fry Get? [updated!]

[SimonSays]

I recently switch all my fish over to a 55gallon tank from my 20gallon( overstocked ), I drained the 20gal and left it sitting around for about 1 week with 1.5-2 inches of water, while I was planning out a diy stand. I recently finished the stand but as I was adding water back into the tank I noticed super super small fry! (as well as many other strange critters). They're very small, smaller than any fry i've ever seen, they're the size of the space in between these parenthesis
( )

They also definitely look like fish, the same form with a tail and such with small dots for eyes and a small dot for a stomach!

are these actually guppy fry?
I have Tetras
Rainbows
and guppies

I tried to take pictures but they're very very bad T_T

i dont think they are fry especially if the female wasnt in the tank

probably some bugs, or larvae

i wouldnt put any fish in there for now untill you know exactly what it is

 

[SimonSays]

hmm actually you're right, my guppies weren't even in this tank, they were in my 10gallon I had...the only fish that were in the tank before I transfered to the 55gal were the rainbows, longskirt tetra, flame tetra, and ottos....so they really can't be guppy fry...hmmmmm but they really really do look like little fish =/ I wish I could get a better picture!

its mostly likely some type of larvae could be fly, mosquito, or any other bug larvae
give that tank a good cleaning with 1:10 ratio of bleach to water and start the cycle all over again discarding the filter media (if u had any in there)

whatever you do DONT use soap to clean the tank

 

[SimonSays]

hmmm lemme post some better pictures for you, I googled different types of larvae and none look like that i'm seeing =/
pics to follow

 

[SimonSays]

some pics...they looked better on the small camera LCD =(

I'm starting to think (or hoping rather) that they're otto fry

When they move, does their tail look like its making a loas of prenounced S's as if it doesnt have a back bone? If so, it is mosquito or some other type of larve. Else, it is probably a fish Not guppy as explained earlier.

I highly doubt they are otto fry, oto eggs are very obvious and the fry stick themselves to surfaces in the tank. Its much more likely they are the fry of a tetra of some sort, most tetras are egg scatterers and lay their eggs in the substrate of the tank when dry or wet season conditions are mimicked (which you could have done unintentionally) in the tank. You should go out and get some food for egg laying fish fry like Liquifry otherwise the fry will start to die off.

use the MACRO feature on your camera to get a clearer picture close up
its the icon that looks like a flower, its for taking very closeup pictures and will give you good clearity

it could be tetra as Tokis said, but most likely not oto fry
add some liquifry and see what they turn out to be after a couple of weeks

Hi,

My Female guppy just gave birth and I have found what I know are guppy fry (now in breeding net) but I also have the tiny fish looking (supposed fry) that look identical to Simonsays pictures.

A few weeks ago I noticed that one of my neon tetras was looking very plump...so maybe it could be her babies.

I've put 3 of the unknown fry in the breeding net (although there are alot more in the main tank, but they're so small I cant get them, so have left them in with the plants and noticed a few in the gravel.

Looks like we've got a surprise when they grow.....now all we've got to do is wait lol

Let me know if there are any changes in yours and I will try and get some pics

They are far more likely to be glowlight tetra fry, glowlight tetras are easy egg laying fish to breed, on the other hand neon tetras are moderately difficult fish to breed and are unlikely to breed in the average community tank set up.

any updates to what htey are

 

[SimonSays]

Well, I've been in and out of my apartment since i'm working about 2 hours away, after the first 2 weeks away, most of the fry ended up dying since I had no way to feed them =(

but 3 survived!

These are some pics of the 3...I actually still have no idea what they are, we're thinking glass tetras? or maybe rainbows? I'm not sure, they're still see through like the glass tetras but they seem to have an elongated body like my rainbows...any ideas?

Hello, interesting post! Any luck identifying them as of yet?
