There's a huge difference between 20 and 35 gallons, but as long as you stick to 2 inch fish that won't matter.

I wanted 1 for each sized tank

I asked the same question on another forum some time ago, there are lots of fish that stay grouped but few that have a real tight schooling behavior. It seems that rummy-nose tetras have the best schooling behavior.

20g is kinda small for that, you see schooling behavior when fish move but they don't have much space in 20g. I can suggest lampeye killies, I have kept a group in my 20g, they are very cute fish, stay small, very peaceful and stay mostly grouped.

OK for 30-35 gall

My rasboras stay together sort of in a 29 gallon, now that there are 10.

I think danios school the most tightly. Smaller types like celestial pearl danios or danio tinwinii may work if you like the look of a large group of tiny fish.

Espei Rasboras are nice. I have 7 of them in my daughter's 20g.

In the 20 you can put neons. Mine stay together most of the time. I get a straggler or 2 every so often.

In the 35 I love my rainbows. Dwarf neons school all the time.

Strawberry rasboras are quite tiny and they school very tightly. I've got about fifteen of them in a ten, they are charming, mid level swimmers and only now and then do I see one by itself. Usually they are all together, all the time. Very cute, peaceful and it's not too hard to tell the sexes apart either. They have a black spot on their sides, and in males it is distinctly larger than in females, along with the usual physical differences, like fuller and rounder belly on females. So unlike many fish, you can sex them with reasonable ease even though they are very small. Less than one inch full grown. Not quite as brightly coloured as Chili rasbora, but very pretty.
