I feed a small amount (they eat it all in less than one minute) several times a day (2 or 3 times) Since i am feeding a couple times a day i do a extra water change each week and rinse out the filter cartride every 3 or 4 days to make sure i dont get alot of garbage in the water. Has worked well for me so far. They were so tiny when i first got them , true fry, they were so small i was suprised they could ship them that small. In one month they have grown to the size my burundi fronts were when i purchased them in the LFS. I bought those at the 1-1.5 inch size and these are mostly at 1 inch or slightly under now. I feed both sinking mini pellets and flake food, i also give them one tubiflex square a day, thats the treat i give them to teach them to hand feed, they love it and swarm around my hand , tearing off chuncks of it, going inbetween my fingers and sitting in the palm of my hand . Its great. I hope they will start doing that again, they are a bit afraid of me now that i moved them.
