Dwarf Gourami Questions

so I have a 29 gallon tank and I already have a powder blue dwarf gourami, I'd like to add a blue and orange one. I have seen that they can't be together but how come they are housed together before they are sold? Is it not possible to keep 2 in a 29 gallon tank

 

Solo. 29 is too small for keep 2 male gourami. Unless it’s heavy heavy heavy heavy vegetated. You got what I mean.

 

I do get u. I was just wondering how places can sell them with multiple in the tank.

 

They don't get really aggressive with one another until they reach sexual maturity. The ones you see at the fish store are always pretty young.

 

Thank you. I was really trying to get a blue stripped gourami but my impatience won over and I settled for a powdered blue. He's beautiful but of course after MONTHS of looking I finally found some and I'm kicking myself. Hence the questions.

 

These are called neon blue dwarf gourami. Powdered blue is also nice.

I know this because I actually bought two neon blue for my 29 gal. End up returning one because they just keep fighting. And I have a lot of plants to cover. So I would not risk it.
