To update my earlier comment: all breeding attempts were unsuccesful. After about 3 weeks all babies died. After several failures, I gave up and gave new nests to my newts, so that they could feed on them. Amazingly, about one and a half month later, I found out that 1 gourami egg actually hatched. A small gourami was living in my newt tank and somehow survived the newts, the colds (19°C) and a 50% weekly water change. I fished him out immediately, but the only tank suitable for him was a tank with Danios with heavy current. Even more amazingly, even that didn't bother him: one month later he has grown a centimeter longer, and bosses all the danios around.
Colisa chuna/honey dwarf gourami do enjoy small dry foods, but prefer small living foods, especially crustaceans. Funny thing is, as one person said here, mine have a tan body with yellowish cast; the dorsal fin of the male shades from plain light brown to gold dark stripe on sides. They are similar to dwarf gouramis but they also use less vegetable matter in the construction of their nests. One last thing to note is that the males are more tolerant of the hesitancy of the female to spawn, whereas the male Colisa lalia will damage the female if she is not provided with enough refuge. Temp 22 to 28°C is fine for this great fish, peaceful and shy.
The gourami pictured is a lovely specimen of the "gold" honey variety. Honey gouramis are also available in red, as well as in their true colors. The true colors of females are very bland, however the male has a black stripe running from his chin to his belly and his dorsal fin has a beautiful yellow color, effectively giving him a stripe on top too. His body ranges from gold to red or maroon, and he keeps his color best in the presence of females. All varieties are the same species and can be interbred, although I find that the red variety gets larger than the other two. I have not had any trouble with them eating plants, but they do seem to pick at algae.
I acquired four of these beautiful fish about five months ago. When I was buying them, I asked if they knew the difference between male and female. The answer was "No, they all look the same". Well, as luck would have it, I've ended up with two perfectly suited pairs! I can't believe the delicate colours that the males take on when in breeding condition. They seemed to become ready before the females, and only now are the females "plumping up" in readiness for spawning, I hope. Many bubble nests have been built throughout the plants. I keep them with 2 Chocolate Gouramis, 4 pygmy corydoras, 3 Otocinclus and a small school of Emerald eye Rasboras. This all makes for a wonderful "miniature community tank".
These fish seem very susceptible to dropsy, an easily identifiable disease which is characterized by a noticeable large bloat in the abdomen and scales protruding from the body. Scientists have not identified the cause, but they think it is caused by some sort of organ failure. I had to treat my tank three or four times with Kanacyn, which is a wonderful treatment although it can crash a biofilter, being an antibiotic, but now my tank seems to be working fine. These fish truly are a perfect beginner's fish, because they are hardy, adaptable, and don't have any special dietary needs. Other than that, they must have some vegetable matter in their diet and should not be fed live food regularly; their digestive systems aren't made to handle that. Another strain of this species is the honey sunset dwarf gourami, and it is more of a pinkish orange, although some specimens have a brown mark on the face and abdomen.
These are one of my favourite fish out of all the freshwater fish. They are small, colourful and very lively. They have great personality, swimming through leaves, through small holes, picking up gravel with their mouth and darting from side to side of the tank. I have 3 Gouramies in my 60 cm community tank. They live alongside guppies, mollies, glass fish and one Angel fish which seem to get on very well with my flame honey gouramies. I've had my gouramies for two years now and, gathering from what I have read, I think one's a male as he is darker than the others. I have decided to try and breed them which I am very looking forward to. I have already bought a 75 L tank filled with a wide variety of plants for the male to build the nest out of. I have also added an upside-down, small plate and a few rocks to help build the nest. I just hope all goes well.
