Smallest/Dwarf-est Freshwater Schooling Fish

[Shadow]

My guess for 2ft tank, 12 is too small, they scared/stress and hide. 20 is just nice, big enough group for them to go out swim around. However the group are not too big, they still feel scared/stress and group together tightly to comfort each other. 50 too many of them, what ever they go they see each other so no need to school.

In my 2ft tank, there's a magic number to have. Too few and they just hide and never come out, too many and they don't school. I've about 20 of them now and they keep together in a rather tight group. Before that I had 12 or so, and they didn't school.

This is basically pure luck. Many had proven the magic number theory wrong.. Haha

[|squee|]

So it's a hit or miss affair? Schooling fishes are very important!

Magic number does not keep them in a single solid group. Anything above 6 will make them school more often.

Or in 2 groups.

Bro Felix, certainly schooling fish will school more often if their quantity is more than 6. However, to test out if there is really some theory regarding the magic number, we should test out using close numbers.
I.e. let say if the magic number deemed to be 18, then we need to see the difference with 17, 18, and 19 schooling fish. And see if with 18 fish, the schooling effect is indeed better than with 17 or 19 fish..

I doubt 1 fish will make any different

[Solasido]

May be to make them school we should introduce a fear factor into the tank (e.g. A more aggressive species)

piranha anyone

Magic no have
Reason. Lfs lol if go there buy 1 tetra.

IMO smaller and larger numbers look better.

I have only got 10 ember tetras and they school in a tight group in my 2ft

[tranzy]

will different tetras school together from experience? eg. Ember and neon?

[stormhawk]

Different species may school together from time to time. However my Cardinals do not school with the Ember Tetras. In fact they never school in my 4 ft tank, just going to any part of the tank as and when they like. Granted, I only have a small number of each type but the only time they ever get together is feeding time.

Ember/Amber Tetras are perfect for this purpose in nano tanks with some suitable tankmates.

Dwarf rasbora (Boraras maculatus), boraras brigittae, Galaxy Rasboras will not school. Golden tetra can grow same size as neon/cardina tetra (5 cm).

What is the maximum size you are looking for? I tried the following fish, the school very well. Ember tetra (2 cm), Sundadanio axelrodi (2.2 cm) and Green Neon Tetra (2.5 cm).

I know this is an old thread, any idea where can I find Sundadanio axelrodi in Singapore?

[Ken_ng]

What about cory hastatus? Mid level schooling cory?

[Ingen]

Found some Sundadanio at C328, unfortunately only 5 blue ones left and decided to try out before their next shipment. One was almost dying when still in the pack (died within 10mins), while another wasn't swimming very well before lights off. This morning, only found three swimming against the flow. Unlike the Galaxy Rasbora, they are constantly in the open (which is great).

I must say, they have a very unique look and very slim (skinny in my opinion) seems different from most of the pictures I saw on the net lol. Planning to get 15-20 of them when the next shipment arrives, hopefully they will start to school tightly.

[gum]

when is the next shipment?

[Ingen]

Probably next week, lets keep each other updated if you happen to drop by and try not to buy everything, leave some for me lol.

[gum]

hahahahhaa just went and i bought
