Dwarf Gourami - Trichogaster lalius
Updated May 13, 2020
Author: Mike - FishLore Admin
The Dwarf Gourami originates in the waters of India and is not only beautiful but they can be particularly hardy as well. The male is more colorful while the females are less colorful. Usually the female is gray in appearance. There are a couple of color varieties including the Blue and the Flame Red.
They make a great addition to a fully cycled community tank and are easy to care for in general.
Some hobbyists find that these gouramis tend to be a bit too aggressive with conspecifics and choose to keep one to a tank.
They should accept most fish food including flakes, freeze-dried, frozen and live fish foods.
If you notice the coloration on your gouramis starting to fade, try supplementing their diet with freeze dried blood worms or live foods once in a while. They are not picky eaters.

Dwarf Gourami Tips and Comments
I put one in with 3 balloon mollies and it picks on one of them, did I make the wrong decision about mixing the two?
There are a few things you can try. The first option is to get another one (if you have enough space). Another one may create a diversion for the one you already have. The second option would be to return the fish to your local pet store if its aggressiveness continues.
Will this fish be compatible with frontosa. I have six frontosa that are three inches in length and I'm looking for suitable tank mates for them.
I have a dwarf gurami which has scales missing on several places on the side of his body. Where the scales are missing it is red. What is it and how do I treat it?
I have a 20 gallon tank that is home to 6 neon tetras, one glo-lite tetra, two zebra danios, and one ghost glass catfish. (the last three species are survivors, i'm not getting any more of their species) I also, if possible, am going to get a bristlenose pleco. If i were to get a dwarf, would it be overstocked? Or could I get either gourami or pleco? Or no pleco at all?
As adults all of your current tropical fish will total about 17 inches of fish. If you add in a Bristlenose (adult size ~ 5 inches) and a dwarf gurami (adult size ~ 3 inches) you will have around 25 inches of tropical fish in your 20 gallon. This would be an overstocked tank, but if you are set on getting more tropical fish just realize that you will need to perform maintenance more often.
I have had 2 dwarf guramis for about 2 weeks. One of them seems to have developed 2 cycst like things on it's body, but they are the same color as him and one whitish one on it's eye. He is swimming and eating fine. Is this something he has that can be given to my other fish? What could it be?
In what numbers do dwarf gouramis do best?
I've got three male dwarf gourami in a 10 gallon heavily planted tank with a cave. The only problems I've had is that the blue one hides in his cave all the time while the red one and the stripey one have bubble nest fights... They've actually started getting along much better after I dropped a few Ottos in with them to take care of the algae.
I have a 30 gallon tank and the general rule of 1 inch fish per gallon isn't neccessary. As long the water is being cared for and the fishes being healthy, they should be fine. I currently have 10 tiger barbs, 6 platies, and 2 striped raphael catfishes. After they all were settled, I added two beautiful blue dwarf gouramis (full blue from head to all fins and tail) and they are just awesome between each other and with the other fishes. During the first day or two, do not panic if the other fishes are naturally curious at each other, after that phase, everything will be just great. I highly recommend the dwarf gouramis, because of their size, color, behavior, and the way they bring life to the aquarium.
I just got my dwarf guarami about a week ago. It is a beautiful fish and is rather peaceful. I currently have him in a 20 gal tank with only a juvenile blood parrot and a juvenile chinese algae eater. I plan on moving them all to a 55 gallon in a couple weeks. He keeps to himself most of the time. Every once in a while he gets into it with the parrot who is bigger then him and seems to be a little more territorial as well. Other than that I think he is a fascinating and beautiful fish that is a joy to have!
In my aquarium I have two dwarfs, 3 angelfish, 2 crayfish, 2 clown loaches, 2 red finned sharks (get along fine) 1 kissing gourami, 3 silver sharks, and a paradise fish. These fish are all pretty big. We have 160 gallon tank. First of all, my blue dwarf gourami used to hang around the bottom and we were worrried about him because the red one was so active. But now it's the opposite... Maybe it's just a trait of the fish?
I was just wondering are these fish like bettas in that they like to be kept singly? I would like to get 1 for a 10 gallon aquarium. Also are they ever prone to fin nipping? (I have a betta that would love to be housed with a Gourami) Thanks, I am looking forward to your response.
I find these fish to be very curious, mine will always come the surface if I'm near the tank, whether I have food or not. If I'm testing the water, they will come up and nip at the test tube, and if I'm feeding, they will readily take the flakes from my fingers. Great fish, glad I got them. I have a male and female in a 20 gallon tank.
I have two male dwarf blue gourami's in a 10 gallon tank along with 4 neon tetras and a blue snail. The larger gourami is constanly picking on the other one. I should have read more about these fish before I got them. I'm thankful for all your comments and tips. I'm taking the larger one back today.

Male Pearl Gouramis may bicker with each other, but overall this is generally a good community fish.
