What charitable of fish for a 5 gallon container?
The safest bet to have a good mini- aquarium.
(No bettas or goldfish)
I am a novice fish owner, and is looking for fish that aren't that knotty to take care of.
Danios (several vareities are available and I am not a certain a lethal injection could kill one...)
various tetra species (most require 6+ of hte same genus to be happy)
you could do a plant & shrimp tank (could add 2-3 small fish as well).
as for learner:
a small filter (or air spong)
heater (most likely)
tester for ph, ammonia, nitrite, and nitrate (drop testers are better)
remember 25% weekly wet changes
may want to research:

any fish you plan to get (ph, temp, size, etc)
Best of luck!
you could even get 3 or 4 guppies.
get adjectives males if you dont want babies.
neons - small, need a heater and capably cycled tank, not always very hardy
guppies - small, can live at 68+, so don't have need of a heater in a warm room, similar to a little added salt (1/2 teaspoon per gallon), can multiply and fill up your reservoir pretty fast
mosquitofish - small, like plain gray guppies, not a lot to look at, but they don't requirement a heater and can stand colder temperatures than guppies and I never had them breed as prompt as guppies either in a tank
platys - just about 2 inches, colorful, also breed fast and like a little bit of brackish
paradise fish - like a gourami, but can live at room temperature, individual get one
dwarf puffer - only get in the order of 2 inches, aggressive, so you can't put anything with it, needs good wet quality and cycled tank, likes some live plants surrounded by the tank, this kind doesn't need to own salt
cherry barbs - small, peaceful, males are brighter than females
rasboras - small harmonious, many species, so look up care for each characteristics
there are probably some other ones I'm not thinking of, but that's a decent list
1-2 mollies or guppies. But without doubt no more; you're pushing it as it is, with a tiny tank like that.
Goldfish are out besides, they cant live in a 5gal for very long.
Get some White Cloud Minows, they are small, hardy and dont need a heating system. I have kept them in a 5gal and they actually bred, so they cant own been too stressed about living in the small cistern.
