I have used neon tetras, vietnamese white clouds. The smallest ones I own are ember tetras, which I have had for almost a year and the largest one is about .5 inch when he is well fed. My tanks are overstocked but I have 30 ember tetras in a 40 gallon tank along with other schooling fish
Others you might consider are the microrasboras, they school and look really nice too!

Chili Rasboras are a common shoaler/schooler for nanos

Any of the microrasboras really. Next up probably smaller varieties of tetras.

I have heard that beckford pencilfish will be a bit aggressive sometimes. But other pencilfish are pretty good and a great alternative to tetras if you are bored of them. I have the purple dwarf pencilfish (nannostomus rubrocaudatus) and they are good looking and fairly mild.

if you are interested in indian natives then look out for Horadandia Atukorali, laubuca dadyburjori, Oryzias dancena. horadandia's are super schoolers..i have around 20 in the tank..

How about Danio margaritatus (Celestial Pearl Danio) they only get to 1.5-2cm and would be great as a shoaling fish, plus they are stunning.

Danio margaritatus: to shy, i wanted those initialy, but always hide

i really like the Horadandia Atukorali and the laubuca dadiburjori. These are new to me, i will see at my LFS if they can get those, because i never saw them.

For the pencil fish, not a fan

Boraras brigittae (Chili Rasboras), i'm not sure my set up will be the best for them, they seems to appreciate heavy planted with some shadow area, they seems to be more a biotope fish. but they are nice!!

thks for your ideas!!

I believe CPDs will become less shy in time, it's just initially that they are super shy.

Most of the really nano fish are super shy. I rarely see my ruby tetras or chili rasboras (and there are literally 15 in a 6 gallon). I would say any of the normally sized smaller tetras or rasboras would be a good choice (harlequins, neons, cardinal, rummy nose) though it depends on what your parameters are like. Harder water species might be Dwarf Emerald rasbora, psuedomugils, dwarf rainbowfish.

Hello DP...

Pygmy or Panda Corydoras are very small. Adults are a bit more than an inch. Either would make a good shoaling fish. Stock one for every 5 gallons of tank volume and a minimum of 6.

Tetras are schooling fish. There's a marked difference. Shoalers many times stay in rough groups when they forage for food, but their movements are individual. Schoolers stay in much tighter groups typically during the day for protection. When one fish moves, the others mimic the move.
