These little fish are very nice. They have good colors and are very active. I have 20 of these fish in my tank. It swims mostly on the upper section of the tank. Rarely do I see one go to the bottom. They school better than my cardinals.
I have about 10 of these guys and they school very well. They are very peaceful fish. To be aboe to get the color out of these fish it takes quite a while. As mentioned before the colors start to show once they are established and feel safe. They are very aggressive eaters and will happily take all sorts of foods.
I don't kno why I seem to always buy these fish but I always end up buying at least 4 to 5 ...and usually only one lives ..right now it is pretty big and I have never seen a bigger rasbora as mine anywhere else...about 1.5 inches..its incredible that it survived some hard times when I wasn' t taking good care of it
i love this fish. When i start feeding them they start going crazy to get food very quickly like piranhas, and very active fish. I also like the color, not strikingly bright like some other fish but it blends well with planted tanks.
These are some of my favorite fish, I have one that is 6 years old and 2 others that are 4 years old. They get a beautiful reddish-orange glow that looks great against plants. Mine have done fine in hard water and soft water. They shoal with my white clouds. They can look dull in pet stores, but give them some frozen bloodworms and quality flakes and you will really see their colors shine.
Recently got 8 of these fellows. Really nice temprements and school well. Very aggressive eaters and as Ryan_P said 'they attack the food like Pirhanas!'. Also the colours do become more dense and bright once established.
I picked these as a schooling fish for my 37 gallon. I introduced them into a tank with a black substrate and 1 6500k bulb and 1 color max bulb. The harlequins turned a really nice reddish/purplish color and look awesome(moderate hard water). If only i had a DSLR camera to show these beauties! School very well and swim in the mid level for me.
great fish!! i have a mini school of 6 and i want more. the colors are vibrant and they are comical to boot!! since my tank is near my tv, i watched them out of the corner of my eye for a couple hours and all they did was "play" in my outflow stream. i though a couple had jumped out of the tank, but they just barely broke the surface. those looked like mini dolphins breaching the water....too much!!
Favourite fish of mine, the Harlequin Rasbora will show it's true colour once you bring them home. The orange on their tails will be much brighter once they are settle in. Also, if you're lucky enough, there will be a blueish hue on top of the black marking that shine much like neon tetras. You have to make sure you're buying true Harlequin as there are about three other fish that look quite similar. These false Harlequin are smaller in size and in my opinion, not as good as the real ones. They are peaceful fish but you might find some of the males flaring their fins at each other. It's quite a sight to see when they do this.
It took about a month for my 8 fish to show their true colors. I've had these fish for almost 9 months now. They school very nicely, though at times they can act like my neon Tetras and bully/chase each other around the tank. I have one Harlequin that has no dorsal fin. I thought the fin might grow back once the fish got settled in, but it has not appeared. I just feel sorry for the fat fish, as I assume there may be communication problems with the other school mates due to the lack of the fin. Swimming also looks a little harder for the individual. However after 9 months of TLC and a varied diet, my fish looking amazing, and I love watching the Raspboras eat 8-)
IME, if you feed these fish live food bbs, or freeze dried food, their color will really really come out and be brilliant. I feed mine freeze dried foods about twice a week, for this very reason. The colors pop out in about a week. I love the red highlights in their tail and dorsal fins. It truly is all about the nutition!
