More than 1 gourami in 55gallon?

Would love to hear some experience with the gouramis mix.

i wouldnt. with dwarf gouramis, it is not a good idea to put more than one male in the tank. even with very peacful gouramis like pearls, honeys, and chocolate gouramis, there needs to be caution involved when more than one male is put into a set up.

You might get away with another dwarf gourami in a tank that size if you have enough hiding places so each can claim thier own territory. I wouldn't do more then that. You also might get away with a pearl gourami since they are on the more docile side for the full size gouramis. However, I would not do both. Are you planning this to be a community tank? If so, what other fish interest you? A nice school of larger tetras might be nice such as diamond tetras or bleeding heart tetras. Looking at what you currently have in this tank it does look like a nice community tank set up and the fish I have mentioned would make a nice addition to the community that you already have.

We have 2 male Pinks in the 80 gal.,, so far no problems,,,,

I have 2 dwarf gouramis in my 30G -- I honestly got lucky and they get actually get along quite well, but it was very scetchy for about 2 weeks. I placed 3 caves and heavily planted the tank, and they stay to each other's side.

I also have 2 flame dwarfs in my 75G - They do very well; zero issues.

FYI - Honeys, Blues Flames and Neon Dwarfs (along w/ about 4 other varieties) are all of the same species lalia (most likely anyways) just different color varients.

I have moonlight, blue, gold, honey and powder blue gouramis in a 175g. I added the blue and gold first. The blue being a little larger will give chase to the gold, but quickly loses interest. Its a well planted tank, so lots of places to hide or get away. Truly not an issue at all, the gold just goes about its busines with no concern. I then added the moonlight, being twice the size of the blue, watched him closely. The blue actually seem to dominate the moonlight at first, giving a chase at times. Again the moonlight, like the gold, just swam away into the the plants and such. Now a month later, they seem to have a truce, neither one chases each other, they get along great. Next I added the honey, it was never chased nor chased anyone. And last I added the powder blue. Interesting, the honey which is the smallest, by far, chased him around for the first few days, but now seems fine. So to sum it all up my gouramis seem to being doing very well together. I would think the key is having a well planted tank. Obviously I'm a big fan of the species.
Note, I also have other fish to interact with the gouramis, so this may keep down the chasing or noticing of each other.
