What are the smallest fish?
 

Smallest thing i can think of is dwarf puffers, they are what an inch?

Anything smaller?

Ember tetras about 3/4"

Pygmy Cory (Corydoras pygmaeus) <1"
Tail Spot Pygmy Cory (AKA Dwarf Cory?) (Corydoras hastatus) <1.25"
Scarlet Badis (Dario Dario) <1"

There are also a couple of really small Rasboras and Tetras. Try doing an advanced search at www.aqadvisor.com and limit the results to 1" or 1.5" and you'll probably get a few more.

Endler's and Celestial Pearl Danios < 1"
(the prettiest of all teeny tiny fish, IMO)

Thanks, those are some awesome looking fish.

I had an idea to put a bunch of really small fish in a big tank with big plants.

That would look fantastic!

Common and small would also be Bumblebee Gobi's, Dwars Rasbora, Norman's Lampeye .

But if you wanna see real SMALL look up: Paedocypris progenetica these fish grow to be 7.9mm (equals 0.3") talk about SMALL

Lol oddly enough i was looking at that that Paedocypris progenetica. But id like fish that i wouldnt need a magnifying glass to see, and im almost positive they would be eaten by the filter.

I really do like the scarlet badis but they are kinda pricey for something so small.

Funny as I was on this other website and someone had similar question and these here are the fish they had listed thought I just pass it on here. Hopefully you'll find something in here.

For me Smallest fish is Neon Tetra 2.2cm/0.85 Inches and another is Dwarf Cory 1" and Pygmy Cory 1"-1.2"
