I’m not sure if it’s the smallest but where I work, the Bumblebee Goby is so tiny (but I believe they grow to 3cm). Better for brackish water but I think the subspecies with broken stripes is alright for freshwater (be sure to research that first anyway).
EDIT:
1 inch fish: Dwarf Hatchetfish
1 1/4 inch fish: Axelrod’s Rasbora
1 1/2 inch fish: Orange-Finned Rasbora, Glass Rasbora, Golden Barb, Glowlight Tetra, Swegles’s Tetra, Neon Tetra, Jelly Bean Tetra, Ansorge’s Neolebias, Nagy’s Licorice Gourami, Licorice Gourami, Pygmy Gourami, Medaka
Scaturiginichthys vermeilipinnis – Red-finned Blue eye grows to about 2.5 cm and is native to Western Queensland, Australia and then there’s the smallest fish in the world found in Indonesia in Sumatra, the Paedocypris progenetica is officially the world’s smallest fish at only 7.9mm long, that is less than 1/3 of an inch in water that has a PH level of 3. This is about 100 times more acidic than regular rainwater! This discovery was made in 2006.
But, I doubt if you’ll find any of these at your local pet store. I would have to say that the bumblebee goby or an endler guppy would be about the smallest fish available for the home aquarist.
The smallest freshwater tropical fish could be any of the livebearer or egglayer babies but if you mean the adults,it could be the Pygmy Sunfish or the pygmy rasbora.
As far as ones that you will commonly see in stores (well, stores that carry more unusual fish), celestial pearl danios, a lot of the Boraras species, and badis (Dario sp.) all usually stay under an inch.
well its short and simple, the dwarf dessert gobby fish.
they can get smaller then an inch
