I'm really wanting to set up a Mr. Aqua's 12 gallon long Iwagumi style. What species would be comfortable in a open Iwagumi style tank? There will be a few tall plants, rocks and DW that they could hide by, but it's not going to be like a heavily planted were they would be really comfortable. So what would you recommend?

Schooling fishes, like neons or cardinals...

Check Out ember tetras, mine tend to stay in the open, and are the perfect size for a small tank. You could put a pretty sizable group in a 12 gallon too

What about Rasboras or Rummys?

 

[MissCoryCat]

Rummy nose tetras are cute and small enough to get a decently sized schooling group going in that size tank.

 

[Elliot]

Ok, am I not mistaken that Rummys school together tightly no matter what?

 

[Elliot]

The fish in this video are Harlequins right?

 

[NStarr]

Yes.

 

[kamikazi]

personally I wouldn't put rummys in a tank smaller than a 20 long. they really like to swim back and forth the length of tanks.

I love my harlequins. Like others said, some type of neon or cardinal tetra . I really like the blue neon and green neon tetras you don't see them used as much as standard neons.

 

[Elliot]

I'm thinking that Harlequins are the best to go with. Cardinals and Neon tetras don't school as tightly as i would like them to.

 

[LCP136]

They don't school as tightly, but you could get a pretty big group of celestial pearl danios into a tank that size. I just picked some up for my 36 and they are tiny.

 

[Elliot]

Wow! When I read Pearl Danio, I thought, ugh, it's just going to be on of those ugly Danios again, but no, those things are pretty! Do you have a video so I could see how they do school? I know it's not quite what I was looking for, but it would always be fun to have side school of them.
