World's smallest fish - Natural History Museum

I can't imagine these ever finding their way into the hobby market but I'd love to set up a tank for them and try them out!

*EDIT* Just found another site which suggests they are available!

So how do you know you've got a tank full of them???

Haha, somebody sold you an empty tank telling you it was full of fish, like the story of the emperors new clothes!

Can't find any useful info about keeping them, let alone where to find them. Loadsa questions!

How tolerant would they be of water conditions different from their native Diet Coke, could they be acclimatised to 'normal' water?
Would they take dried food? What do they normally feed on?
Can they be kept in groups, are they territorial?
Can they be bred?
What's their lifespan?

Would definitely have to be a species tank, custom build maybe only up to a couple of inches front to back if there's to be any chance of seeing them.

Being a cyprinid species, they should be quite easy to acclimatise to normal water I would've thought, And as for food, as they're so small, I'd say infusoria would be their main staple, but, something like ZM000 would also be acceptable.. But, this is all just what I'm summizing from what I've read about them.. It may not be true at all!



There's always Danionella species to consider too, which seem to be more widely documented.

Good observations there Nic , but I'm not convinced entirely these could be regarded as 'typical' cyprinids, I suspect your right about infusoria, was thinking along the same lines myself. Would make them tricky to keep long term. I don't know ZM000, what is that? I was thinking about Liquifry No. 2 or similar as a possible.

These fish are classed as threatened in the wild already.

I'm writing to the Natural History Museum to ask about endangered fish species in general and to suggest that home hobbyists could be the answer to conserving threatened species in the same way that zoos are used to conserve tigers - except that worldwide there's maybe only a couple of dozen zoos that can keep tigers but there's thousands of us! How would you like to get involved in something like this? People are doing this already with Madagascan cichlids and L-number plecs. This could be the future of fishkeeping! I mean this very seriously.

Would be very interested in this Ferox, *if* I get into uni, it could go quite nicely hand in hand with that, and could actually be a good starting point for my dissertation. Hmmm...

ZM 000 is a very fine fry food, and much higher in quality then the Liquifry kinds of food IMO. Also, it was originally developed by an ex Sparsholt lad, so the profits aren't just going into the pockets of a massive company. smile Link

I might get some of that food to try it out. Probably just once though - 90g would last me decades!!

Di, I don't think you'd want to keep any other fish in water with a pH of 3! Wouldn't need to be a big tank either, you could probably keep a dozen in a margarine tub.

I think filtration would be an issue with them being so tiny too, any powerfilters would be a big no, as would strongly filters UGF's, which only really leaves sponge filters, as I beleive they'd be small enough to get stuck in a box filter too.. Hmm...

The substrate would I think have to be peat and I'm thinking about the peat bogs not far from here from where both the substrate and water could be collected. These conditions are possibly ideal for this fish if it weren't for the temperature!

I think I'd use a home made UGF box filter similar to one I have in a fry tank at the moment. It's a 4" square box made by cutting down a plastic bottle to a height of 3" or so and using a short uplift pipe and a well regulated air supply. It's very gentle and I've just used it to successfully raise tetra fry from eggs to near adult.

I doubt if much filtration would be needed, how much ammonia are 8mm fish going to generate?
