Name: Badis badis
I just got a group of 6 badis badis burmanicus last week and I put them in a community aquarium. I feed either foods that sink fast and so get to these bottom dwelling fishes or feed on one side of the tank for the other fish and place food on the other side of the tank for the badis. They have all selected favorite hiding spaces, some like holes in the drift wood, others like the PVC I have in the tank, others the cave I have for my plecos. One female has even "learned" that by following my ancistrus around she'll always be near a good hiding spot and will get some of the food it scrounges up. After a week in the tank the two males have colored up, but the females are still quite drab.
In doing some research about this fish, I discovered they were once considered Cichlidae. They are slightly territorial, yet a tad shy. In my experience with them, they only ate LIVE, meaty food. NEVER flake or any type of vegetable matter. They stay rather small, and there is a beautiful scarlet badis available in the hobby from time to time.
An excellent fish that will do great in a quiet community tank, but will thrive in a species tank. I keep mine in a 200 liter corner tank that houses a variety of fish, but my badis don't mind and are doing great. They like some of the frozen foods intended for discus, as well as, any live foods. Mine are nearly weened on to flake, but I plan on still feeding them the good stuff. My male is very pretty, and being a Badis badis burmanicus, has very nice red scales accented with green ones. Overall a very nice fish that, after a little effort is put in, will reward you with dividends.
These fishes are generally shy even among themselves. They are however cute due to their miniature sizes and can be quite difficult to detect among plantation. I tried feeding it flakes and other types of dried food, but they do not seem to respond. However, they enjoy live tubifex worms even if the worm can be quite difficult to consume for their size. Thus, I conclude that they need live food. My advice is do not mix them with big fishes and only insist in live food especially tubifex worms.
The beautiful Badis comes in several varieties, though there are only 2 actual species in the genus: Badis badis and Badis bengalensis. They are of the family Nandidae, not Cichlidae, though they do display some of the same characteristics of the Cichlids - namely the "yawning" and the territorialism. Often times B. badis will not take flake or other dry foods, but they accept frozen bloodworms as well as live or frozen brine shrimp readily. The problem that arises here is how to get the food to them, as the more aggressive fish will probably eat it all before it gets down to the Badis. This, however, is not a problem at all if your Badis are tank-raised or are acclimated properly and will actively compete for food. If you are having this problem though, the best way to get food to them is to melt the bloodworms or brine shrimp in a cup of hot water before you add it to the tank. This way, your chosen cuisine will not be concentrated like it would be if it were frozen when fed, and the Badis will certainly get some. Badis badis spawns in caves, much the same as cichlids. They will not eat the fry, though care should be taken to use only a cycled and establised tank for breeding purposes, so the tiny fry can find food the first few days. Badis badis species grow to 7-8 cm or so, whereas Badis bengalensis grows to about 3 cm. If you can find this fish, get it! They ALWAYS look drab and dull in the store, but the blue and red coloration that results when the fish is acclimated is absolutely striking. The same goes for B. bengalensis, though it is much more red and a lot smaller than Badis badis. Editor's Note: a 2002 revision by Kullander and Britz has classified more than a dozen species of Badis sp. - MA
In 2002, a complete revision of the genera Badis and Dario was done. There are actually 12 species of Badis: Badis badis, B. chittagongis (species nova), B. kanabos (species nova), B. ruber, B. siamensis, B. khwae (species nova), B. ferrarisi (species nova), B. assamensis, B. blosyrus (species nova), B. corycaeus (species nova), B. pyema (species nova), and B. kyar (species nova). Many of the new species were probably thought to be varients of B. badis or B. assamensis. In addition, a new genus was made to house some fish formally classified as Badis: Dario. There are currently three species: D. dario (formally Badis dario or B. bengalensis in the hobby), D. hysginon (species nova), D. dayingensis (species nova). I believe that, as more work is done on both genera, especially on the molecular level, we'll find that both Badis are Dario are far more species-rich than we now assume. Hope you found this interesting.
