Hello! I am going to get a 20 gallon freshwater tank and I am looking for stocking ideas (like combinations of fish). I have had a 3.5 gallon in the past, but this is a huge upgrade. And before you tell me, yes I do know about the nitrogen cycle and will do it. Any help will be appreciated. Thanks!

I have a 20 long with a pearl gourami and appisto cockatuoides that I really like because their colors match.
It’s also has shrimp snails and Pygmy corydoras
How many appistos and corydoras do you have? Also what kind kind and how many shrimp? BTW my tank would be a 20 tall. (24 in wide)

You can try small tetras such green neons, embers, or ruby tetras. As for a centerpiece, you can do honey gouramis!
I was thinking, would 7 neons, 1 pearl gourami and 3 corydoras be overstocked? If not, how much more could I add? (Like snails, small fish, etc.,)

1. I don't recommend neon tetras since they are overbred nowadays.
2. Pearl gourami in a 20 is too small imo.
3. 4 of the same Corydoras species. Though 6+ is better.

Agreed unless you have a 20 long I wouldn’t suggest a pearl, honeys would be a better fit for a tall
I have 1 male pearl and 1 female appisto
I keep bladdersnails trumpet snails and mystery snails
And 9 Pygmy corydoras.
And about 10 young red cherry shrimp that were culls from my breeder tanks.

Which even if you go by the inch to gallon rule is pretty understocked

20 longs have the footprint of a 30 so they are just as much space if you don’t crowd the tank.

I agree with Crispii, except that I would do more cories, the more the better, and you have the room. At least 8 imo, though 6 isn't bad.
