Cut and pasted from Tanks Smaller than 5 gallons... good for anything?
| 1g: Too small for a betta because they don't make any heaters small enough to safely heat a tank of this size. You could go with about 5-8 cherry shrimp, a handful of ghost shrimp (surprisingly entertaining) or a nice-looking snail like a zebra or a ramshorn if you clean the tank well and provide lettuce for them to eat. |
2.5g: You can heat a tank of this size with a small heater (aim for 5w per gallon). The marineland stealth is a good one, but larger heaters (no larger than 25w) can be used on a low setting. A betta would be happy in this size, or even about 3 male guppies*. Another awesome pick is the Endler's Livebearer*, a relative of the guppy that grows only an inch in adult size, provided it's a male. Any of the options for a 1g will also work.
3g: Basically any of the options above. I might also add that the Eclipse comes in a 3g model... the excellent filtration system can handle a few more fish than the average filter.
5g: All of the above. There is also ample room to house a school (about 6) of one of the many kinds of dwarf rasboras (also known as microrasboras) or tiny tetras (anyting under 1.5 inches). Alternatively, you could divide and house two bettas (perfect gift for two kids, less maintenance for the parents). A honey or sparkling gourami makes a good 'centerpiece fish' to go with the dwarf rasboras. You could also have about 5 guppies in a tank like this, very easily with some cherry shrimp on cleaning duty. A few platies* would work as well.
*Livebearers of any sort breed like rabbits, so don't mix males and females! Even if you plan on selling them to a pet store, you still need lots of room to grow out as many as 50 babies per batch.
Hope that helps! As a committed nano-tanker, I can assure you that there are many more options for small tanks. I have only stated the most readily available and easiest to care for. As far as what to avoid, here are a few pointers:
-Absolutely no goldfish, plecos, bala sharks in any of these tanks. All of these guys will reach a foot in length easily.
-Always know the adult size of a fish before you recommend it.
-No bettas in tanks under 2g! They are warm water fish, in fact they prefer warmer water than most community fish! I recommend you read over the betta care sheet ( http://www.tropicalfishkeeping.com/betta-fish-care/must-read-general-betta-care-faq-20058/ )-- these guys are huge sellers
-And last but not least, the bigger the tank, the less you have to clean it!

agree. No neons. Here are some potential tenants: |
One of these
-5 male Endlers livebearer
-6 Emerald eye / green neon tetras
-3-5 Male Guppies
-3 Bumblebee gobies**
-1 Dwarf puffer**
-3 African Dwarf Frogs (possibly?)
And / or one of these (except with ** fish)
-4-6 Dwarf shrimp eg. Cherry Shrimp, CRS, CBS, Pearl Blue Shrimp, Emerald Green Shrimp, Amano Shrimp
-3 Ghost Shrimp
-2 Zebra / Nerite Snails
-1 Ramshorn Snail
* This genera includes a zillion little rasboras that are all under about 1.5". Very cool fish and perfect for small setups. Just a few from this family are: Celestial Pearl Danios / Galaxy Rasboras, Boraras briggitae, B. merah, exclaimation point danios... the list goes on! DOn't forget: keep no less than 6 of the same species.
** For more experienced fish keepers. They are rather messy and will not accept dry food.
Hope that helped! Obviously you will have to fiddle around with the actual numbers if you want to get reasonable bioload but all species should be happy in an Edge.
Sorry for the C&Ps! There are only so many times I can rattle off the countless possibilities for nano-tanks!!!
