You would probably be fine with 5-10 neon tetras.
30 gallon is a big space you could get 6 more but make sure to get male female 1:3
Not very long. We originally started out with 4 mollies in a 5 gallon aquarium. About 3 months later we realized 4 had turned into 17! Now they are in a 35 gallon aquarium and theres more! We have now had many babies, and watched them grow. Takes them about 6 months to become 2 inches long.
Mollies,Platies, Guppies, small Tetras (I recommend Black Skirt Tetras), Corydoras, (Electric or German) Blue Ram Cichlid, and last but not least............ Apple Snails. ;)
Cherry Barbs, Cory Catfish, Zebra Danios, Platies, and some Mollies, but Mollies tend to bite the bettas tail. You have to have a bigger tank if you want to have a community tank. The general rule is 1 inch of fish per 1 gallon. I've also had some luck with the small Tetras.
none because mollies need 5gallons and up
You can put a Otocinclus. But the rule is an inch per gallon so try an Otocinclus all the other eaters will be too big for a little tank.
yes
as many as you'd like.
That would be a standard 29 gallon aquarium
Half gallon is miniature! it is cruel to keep a fish in a tank that size. I would definitely recommend getting a new, bigger tank. A 10 gallon would be ideal, fish options could be guppies (even though they breed like crazy) mollies, sword tails or platies.
You can put one maybe 2 one-inch fishes in your one gallon aquarium
