What to do with small harlequin rasboras, fry?

[Fishkeeping7777]

So if you read any of my other thread you know that I have is really bad luck so far with Harlequin Rasboras.
I went to a pet shop that had them pretty far away today, I got them but I was kind of disappointed because they were so tiny there fry.
I wanted to put them in with my guppy that’s in quarantine but I think he will eat them.
I have this tank 2 1/2 gallon that I’m waiting to get fish for.
I asked someone to buy them for me, they never did so I was going to, by the way it’s online so I know they need a cycle tank.
I’m gonna put them in there after it gets up to temperature, it has alive plant so I can’t add aquarium salt or medication.
If one passes away what do I do, a big water change?
I don’t wanna crash my cycle

If the rasboras are bigger than the guppy's mouth they should be fine in the same tank. If they really won't work together for now though, you could cycle the 2 1/2 gallon in a day or two if you take some of the media from an already cycled tank and put it in the 2 1/2 gallon's filter.

So I know that there’s a lot of auto cracks but the 2 1/2 gallon is cycled and I already put them in there the reason why I didn’t put up with my guppies right away because the course I want is it to be quarantined and I have all Male guppies so they’re just going to gang up on it today they were fighting over a piece of algae wafers for my snail in serious fighting to so I know if one of them crosses my guppy wrong it’s gone for the Rasbora so I rather them get a little bigger before I put them in there

One of them can almost fit in the guppies mouth so I also don’t want that to happen they’re about the size of maybe a quarter of a penny or half a penny I’m not good with measurements

So I need help. I Bought Harlequin Rasboras yesterday .They’re all fry so I heard they needed a cycle tank even if it’s just for quarantine and that’s why I’m another ones were dying.
I put them in those 2 1/2 gallons cycled planted for one another fish I was getting and no it’s not a betta
They’re acting fine yesterday eating having the greatest time swimming around schooling wake up today and I’m concerned because I only see three I looked everywhere there’s no fourth one and plus my tank is 99 detritus

so I looked today and there’s no ammonia though in the tank but I’m noticing at their schooling right now and there’s not a fourth one.

I really don’t want to have to take apart my whole set up that’s been like this for about two months and just crash my cycle and uproot my plants so what do I do
So the ammonia test got done and it does look like there is very little maybe idk

I finded him on the floor RIP

Oh I remember your posts.... Did you put a heater in ur 2.5g quarantine? That will make the water way too hot...

99 detritus? Or 99 degrees? The fish will try to jump out if it is too hot

99% detritus

Most fish will jump out of a 2.5 gallon it's just way to small. Not a fish tank size
