How many fish total can I put in a 15 or 20 gallon aquarium?
I usually go by the one gallon per one inch of fish (grown). Does this still apply? Only fish in the aquarium will be fancy guppies, neons and zebra fish.
Thanks.

"I usually go by the one gallon per one inch of fish (grown). Does this still apply?", No, it is actually a myth, so don't use it even for grown fish.
3 fancy guppies - ensure that they are ALL male, otherwise you will have an overstocked tank.
5 neons
3 zebra danio.
Try an algae eater too, like a nerita snail or bristlenose.

The one inch per gallon is only a guideline it doesn't take into account whether its a slender fish like tetras, angels silver dollars or a fish broad fish like catfish, puffers, guppies or a tall fish like again angels or discus, i use a 10 gallon for 4guppies and their fry and in my 20 gallon i have 6hengrls rasbora, am gettimg 3otocinclus catfish amd have one juvenile ram which I'm getting 3more but will be getting a 50 gallon before they are full grown in the next couple month's but that's it for stock

depend on how big ur fish. normally 1 inch goldfish per 3 gallons water. You may ask pet owner for an advise.
