I'm pretty sure the danios are that way naturally. The species is Brachydanio kerri, while Zebra Danios are Brachydanio rerio.

Pearl Danios are just a variant of Zebra Danios.

Puma, are you referring to keeping rainbows in a 10g? I wouldn't suggest this as they are BIG on swimming space. A 20g is probably the smallest id' feel comfortable putting them in. rainbowfish really like their space.:)
 
Well now, I guess if I were literate I would have realized that lol. Please disregard my nonsense...but do pay attention to not keeping rainbows in a 10;)
 
Not a big pleco fan,sorry. I would recommend the Zebra loach (boita striata). Very friendly and gets along great with yo-yo loaches IME.
Honey gouramis are more docile.
True >1 dwarf gourami (male) may not be friendly to each other, but in a tank that size you shouldn't have much trouble with 3 or so.
