Badis are a peaceful species, though best kept in a species only tank due to being territorial after spawning. Badis are particularly helpful at reducing snail populations should they pose an issue in a tank. They are a shy, tiny, tropical freshwater fish considered one of the more underrated species in the hobby, neglected despite their brilliant coloration, stripes, and unique personality reminiscent of dwarf cichlids that make them quite an interesting species to keep and watch.
Male Badis look a bit slimmer than females, and their pelvic fins also extend out further as they develop and mature than those of the female.
Males are also more colorful than females (which are without the red or blue colors on their flanks), making them the more popular sex for importation. The Badis come with seven bold stripes along their body.
Badis prefer the best of both worlds: well-planted tanks offering lots of hiding places and dark “secure” areas between rocks and wood, as well as open swimming areas to move around in. Using the water conditions above should render very healthy and vibrant Badis.
Badis accept all varieties of food from the staple quality flakes, to blood worms and white worms as treats.
Best kept in a well-decorated set-up with aquatic vegetation and woody structures. The addition of some floating plants to diffuse the light entering the aquarium also seems to be appreciated and the addition of dried leaf litter can add a natural feel. Filtration, or at least water flow, should be relatively gentle, and use a soft substrate if possible since Oreichthys species have miniscule sensory bristles on the lower jaw which are used when foraging.Unsuitable for most community aquaria as it may be intimidated or outcompeted for food by larger or more boisterous tankmates. Small, peaceful cyprinids such as Trigonostigma or Boraras species make good choices and we suspect it will also do ok with many South American characins, Otocinclus or pygmy Corydoras catfishes. Potential additions from the Ganges basin include Badis badis, Pangio pangia, and Colisa chuna. Although gregarious by nature it’s a shoaling rather than schooling fish which develops a distinct pecking order and rival males will exhibit some interesting sparring behaviour in captivity. It’s best maintained in a group of 8 or more but the tank must be decorated in such a way that many broken lines of sight are provided. If kept singly, in a very small group or in cramped conditions it can become withdrawn and subdominant fish may be bullied incessantly. Will accept dried foods of a suitable size but should not be fed these exclusively. Daily meals of small live and frozen fare such as Daphnia, Artemia, and suchlike will result in the best colouration and encourage the fish to come into breeding condition.
