What are the best benign of fish for a 5 gallon container near no kiln?

this tank was used for a beta, but i would like to try something contemporary
try using guppies and platys and mollies and other small fish resembling zebra fish that are a part of the minnow family but u still need a nouns pump or the fish will die because they need oxygen in the water
Some White Cloud Minnows would work, but they will inevitability a filter and regular water changes.

The tank is for a moment small, but it can be done. Mine bred in a 5gal, so they cant have been that stressed.

Shrimp may be another choice, but the common species will need a heater. There are coldwater species though.

Goldfish are desperate choice, they just grow too big.
okay what happend to the heater you had when you had your betta

the solely option i can think of is Phalloceros caudimaculatus, Leopardfish

I have a betta in a cistern less than 5 gallons and it doesn't have a heater. it have lived for 5 YEARS! not joking. or just get a goldfish. dance to www.aquariumfish.net they have lots of good fish choices.
goldfish are cold water fish and cannot live within a bowl because they create more waste than other fish. Try keeping a fancy goldfish.
I agree with Gary - White cloud mountain minnows. They are cold dampen fish and have some great fin-flicking dances to watch.
I keep goldfish and guppies short a heater
White Cloud Mountain Minnows, repeatedly called just "White Clouds." They are small and beautiful and they do powerfully down to about 60 degrees F. You could keep 5 or 6 within a 5-gallon tank.
I would definitely get a dwarf puffer beside some otocinclus. Dwarf puffers prefer warmer water but it will probably acclimate to colder conditions. Btw, dwarf puffers are little one inch freshwater pufferfish that are cute and cool and are relatively easy to pilfer care of.
gold fish guppies ( neon tetras and clown fish and bettas involve heaters and bigger tanks)
Nothing... a betta is the only thing you can put contained by a 5 gallon, and it needs a heater.
plastic ones..
Answers:    Just to clear things up- goldfish cannot be kept in that tank, no matter what benign they are.

White clouds are your only option for an unheated five gallon tank.
Maybe a small fancy goldfish or a few guppies. :)
Just make sure the hose doesn't get too cold now!
glass or plastic fish will go best.
Two or three small "feeder" goldfish. Good luck.

Should you attach saline every time you do a river revision?   When will my platies tender birth?   Are tropical/salt marine fish difficult to save alive?   I own lots of white things surrounded by my fish reservoir they look close to eggs but i do not enjoy any snails?
