Maybe worth getting something that will eat any more fry.
That’s all well and good and the adults should do this, but the design of the tank has a sneaky little holding area ahead of the filter which is guarded by a simple grate. It’s just big enough for the fry to get through and find shelter from being eaten.Crossflow Kid said:

At fry age, they'll last 10s in air.

White cloud mountain minnows are definitely suitable for unheated tanks, and what I think the shops should be selling people if they're telling them they don't need a heater. The platies are a bit more borderline, may be OK in a warm, stable room, but we can see the difference that adding a heater made to the OP's fish.
White Clouds need unheated - around 19-21C.However, that doesn't make them easy!
Naturally, they live in fast flowing, very clean and highly oxygenated water.
A "normal" aquarium is not the place for them!
They are however, utterly stunning, and look incredible in a 'biotope' type tank setup specifically for them.
Yep. It's bullst.
They get recommended, as they stay small. So a cheap small aquarium can in theory be fine.
As this thread proves - most fish shops give zero fks about welfare or ethics.
That danio tank sounds awesome! I've toyed with the idea of building a paludarium type setup out of acrylic for something similar - hiding the pumps etc. under the 'earth' mosses/lichens are grown on.
Lots of maintenance though, and high evaporation...

You can buy them commercially with an app to tell it when to "rain" and lighting effects.They get recommended, as they stay small. So a cheap small aquarium can in theory be fine.

I too have thought about this with massive planting and maybe some small lizards...a bit of a rain forest in my kitchen

So what are we talking when we say “fry age”?The current batch that need thinning out are probably about a month old and getting on for 15-20mm long.

Ideally, I'd whisk out as many as possible as soon as possible after birth.
It's st - but unfortunately pretty necessary. In the wild they've a huge mortality rate - hence how prolific they are.

That size, and I'd euthanise in clove oil.
Ok, thanks.ETA: what concentration are we talking? I’ve heard 400ml per litre of aquarium water which seems a lot, especially given its price.

Yep, that’s the plan from now on.Edited by anonymous-user on Friday 24th January 15:44
Clove oil or buy MS-222 or 2-phenoxyethanol from Sigma. Or blunt force trauma.

Laboratory fish I used to use MS-222 or 2-phenoxyethanol overdose. To be honest, in the field, with fish up to a couple of cm long, we just used to drop them straight into 90% ethanol. They were dead within seconds.

Stop it. Just stop it. CFKJnr is gonna be gutted when some are “missing” https://www.practicalfishkeeping.co.uk/fishkeeping...

It's grim - and I can't remember how old jnr is - but it can be a useful lesson about the natural world...
After all, in the wild they have that many babies because they get eaten by other fish and predators which let's those fish and predators to grow to have babies themselves.
Unfortunately, we don't want proper predators in our tanks, and so sometimes we have to 'play Gaia' (insert deity of choice.
Far better than the typical end result of a couple of generations of inbreeding...

Reading a bit more of the guide linked to above, it seems chilled water is humane for small <5cm fish.
I’m thinking...run off some existing aquarium water, capture all the unlucky ones then just leave it outside to cool overnight?
Looking at the way the original fish declined without a heater (ie just became less and less active) it would make sense.

That or Clove oil CFK.....
As a BTW, Im collecting my first ever Marine tank tomo, and plan to run a thread on it - Ive kept trops for over 35 years and never been brave enough to go salty - now is the time....
If you think your journey has been hard, watch this space as they say.....

Will be following for sure... 25 years for me, and I have a perfect spot in our new gaff...
And yes, a completely different ball game - even with a very good source of clean natural salt water fewer than ten minutes away...
