I keep 3 males and 2 females [ badis badis badis ], the picture posted in dwarfs reply is 1 of my males .
My fish do fine with PH just above neutral with moderately hard water [ what comes out of my tap works just fine ], though it is said they prefer the water on the softer and more acidic side .
That being said they are undemanding in respect to strict water chemistry .[I.M.O]
My tank temp is 78 Fahrenheit , 76 to 80 would be fine .
Water current shouldn't be to fast , and water should be changed regularly
Mine breed pretty readily , they spawn and the female leaves the male to guard the eggs [ to raise fry you would need small very small live food ] I have yet to try and raise any fry . cichlid like courtship .
Mine won't take any kind of prepared food [ dry food flakes ], they will eat freeze dried blood worms and freeze dried brine shrimp , but would prefer live food . I haven't tried any kind of frozen food yet , but I'm sure they would eat frozen brine and blood worms .
Badis are a sub member of the perch family as are cichlids , the badis was actually classified with labyrinth fish such as gouramis , bettas etc .
They are currently classified as a member of the nandids , which contains 2 species of leaf fish and the badis .
once thought to be a single species more different species have been discovered [I will try to provide you another link or 2 link ] including darios .
I find their behavior to be similar to that of cichlids .
They can be territorial mainly among themselves so provide plenty of cover in the form of plants , rocks , caves and even drift or bog wood , faster fish will easily beat them to food put in the tank , so choose tank mates that aren't to fast .
check out my sig , these fish have been together since June and get along great .feel free to PM me with any questions
