Food Fed to Parents and How Often*   Tetramin flake food daily, Live baby brine shrimp twice a week.  Live black worms as a treat every 2-3 weeks.

Indoor breeding and raising strategy:  I have bred these multiple times.  I leave the parents in the 10 gallon tank with several Medaka Mops.  Every couple days I remove the medaka mops (replacing them with fresh mops) and put them in a 2.5 gallon aerated tank with a couple drops of methylene blue and an almond leaf.  I add more mops with eggs for a week or so.  After an additional week, when I start to see the fry, I begin feeding them sera micron powder once or twice a day.  Also baby brine shrimp when available.  When the fry are of decent size I remove all the mops and move the fry to a larger tank.
