medaka care
here are some helpful tips for keeping medaka. this page does not serve as a catch-all or complete guide for medaka care, but it should help you to get started if this is your first time learning about medaka!medaka are generally very hardy, but that does not mean that they should be kept in poor environments. at minimum, the following parameters are acceptable for keeping medaka happy and healthy:- one gallon of water per fish in small tanks, or a half gallon per fish in more spacious / enriching environments (more on this below)
- a stable water temperature between 65 degrees and 85 degrees fahrenheit
- a pH between 6.5 and 8.0
- nitrates below 25 ppm
- semi-frequent water changes with r/o water or distilled water treated with mineralsmedaka are small, but they can eat quite a lot! they eat food from the water's surface and can enjoy a variety of treats. our preferred feeding schedule is three small meals per day for juveniles and adults. they enjoy flaked food, bloodworms, baby brine shrimp, and many other treats!medaka fry (hariko) cannot ingest large foods and should be fed specially formulated fry powder, paramecium, photosynthetic bacteria, and green water.medaka can be kept indoors and outdoors as long as the appropriate conditions are met in their environment. should you choose to keep medaka outside, please allow them indirect sunshine for 8-12 hours a day, keep the water level a few inches below the top of the pond or enclosure, and provide adequate protection from predators.regardless of where you keep medaka, their water should be aerated and kept gently flowing to provide enough oxygen and to discourage bugs from depositing eggs or larvae into the water. while some medaka like to eat mosquito larvae and serve as excellent pest control, others are very disinterested and will not eat anything beyond their typical fare.medaka are a schooling fish and are not typically aggressive when kept in an enriching environment. providing a lot of plants and decorations for your medaka will give them visual boundaries and safe places to retreat to if they are feeling stressed. should you choose to add tankmates, make sure you keep in mind the temperament of the species you wish to add and their required parameters to ensure a good fit.
