FrozenFins Posted April 12, 2021 Share Posted April 12, 2021 What size is a nano tank in your opinion? Mine is anything under 10 gallobs. Link to comment Share on other sites More sharing options...
Just a Pygmy Corydora Posted April 12, 2021 Share Posted April 12, 2021 Same here. Probably maybe even 8 gallons or lower, my biggest tank is a 5.5 gallon tank. 1 Link to comment Share on other sites More sharing options...
CorydorasEthan Posted April 12, 2021 Share Posted April 12, 2021 A nano tank to me means any size setup that houses only tiny inhabitants (around 1 inch). This is a bit of a controversial opinion, but if I were to do a nano tank, I would actually not prefer a high tech, delicate carpeting aquascape. I instead would prefer to just do a long tank (20 long), or a 40 breeder and make it a jungle type aquarium (I've be starting to lean toward these recently). Limiting oneself to tiny fish allows for not only large numbers of inhabitants, but also a very large variety. 3 Link to comment Share on other sites More sharing options...
lefty o Posted April 12, 2021 Share Posted April 12, 2021 like above, nano for me is fish that stay under 1.5". big tank equals more tiny fishes. Link to comment Share on other sites More sharing options...
Jungle Fan Posted April 12, 2021 Share Posted April 12, 2021 5 gallons or lower. 1 Link to comment Share on other sites More sharing options...
Eric R Posted April 12, 2021 Share Posted April 12, 2021 I think in freshwater, it tends to mean aquariums around 15 gallons or less. Funny enough, for saltwater nanos seem to include anything less than 40 gallons, where picos are less than 5 gallons or so. 1 Link to comment Share on other sites More sharing options...
Jungle Fan Posted April 12, 2021 Share Posted April 12, 2021 I remember when the smallest commercially available tanks were 10 and 5 gallon before the term 'nano' entered aquarist vocabulary they were just referred to a small tanks. Link to comment Share on other sites More sharing options...
DSH OUTDOORS Posted April 12, 2021 Share Posted April 12, 2021 I agree with @CorydorasEthan and @lefty o. Its about the size of the fish not the size of the tank. My current "Nano" tank that just got fish yesterday is a 38 gallon tall. I have a number of tanks between 3 and 10 gallons but this is the only one i affectionately call the "Nano" tank. I can't wait to get it fully stocked but for now it has 8 CPDs, 10 Chili Rasbora, 6 Emerald Rasbora, 6 Asian stone catfish, 5 endlers (2M 3F) and a few Neon Blue Goby (them being the largest and only there for detritus cleanup after setup) 1 Link to comment Share on other sites More sharing options...
Patrick_G Posted April 12, 2021 Share Posted April 12, 2021 Funny how I consider a standard rimmed 10 gallon a full size tank, but my 11.3 gallon frameless cube a nano tank. 1 Link to comment Share on other sites More sharing options...
H.K.Luterman Posted April 12, 2021 Share Posted April 12, 2021 I'm in the 10 gal or lower is a nano tank crowd. 1 Link to comment Share on other sites More sharing options...
CT_ Posted April 12, 2021 Share Posted April 12, 2021 I really wish people wouldn't jump on the smaller metric prefixes so fast. nano leaves so little space to go for other words. Across the internet I've seen 20g and less be called nano but I wish >5 to 20ish could be called mini or micro. And nano could be used for tank sizes that you "shouldn't" keep fish in. like a 2.5g. I've seen some amazing sub 5g tanks with a few very tiny fish that I just love but we don't have a commonly used word for those. I think about the 2.5g long tank in ACO too much. If there was a how-to video on that tank I'd buy everything in there and remake it at home, but right now they look too intimidating. Link to comment Share on other sites More sharing options...

Marc Posted April 12, 2021 Share Posted April 12, 2021 Small fish not the size of the tank. Anything under 10 is just temporary(raising fry, breeding, hospital) or for shrimp. Even 10 is pushing it as too small for a perm home. Link to comment Share on other sites More sharing options...

Streetwise Posted April 12, 2021 Share Posted April 12, 2021 (edited) The descriptions are varied, and I don’t have a strong opinion. I label my 20 gallon units as nano tanks, and my 7.5, 3.5, 2.5, and 1.25 gallon tanks as pico tanks. For marine tanks, I think that folks consider filtration based on size. For freshwater, it might be more about the minimum size for common fish. Perhaps Angel Fish would represent moving bigger than nano.

Fish Folk Posted April 12, 2021 Share Posted April 12, 2021 5.5 gallons or less is proper “nano” . . . but I’d say most of what we keep qualifies as generally “nano” . . . 20 gal or less. I think once you get to a 29 gal, you’ve leveled up. Link to comment Share on other sites More sharing options...

Pico is a commonly used term to describe reef tanks 5 gallons or less, since they consider nanos to be much larger. 1 Link to comment Share on other sites More sharing options...

PlaneFishGuy Posted April 13, 2021 Share Posted April 13, 2021 (edited) I voted 10 gallons or less - but only because I read it somewhere. 20 years ago before I left the hobby I'm not sure I would have even known what "nano" meant, but I probably would have answered tiny beta bowl or shot glass back then....
