Just picked up 3 pair of adult millenium rainbows from a local reputable fish store.All fish are healthy and housed temporarily in 65 gallon...soon to a 100 gallon.I've had them a week now and they're still extremely skittish..unlike any rainbows I've previously owned.I threw in about a dozen 1 inch bicolor 500 cichlids.This has helped to settle them down a bit.Anyways...I can only get them to eat bloodworms and brineshrimp.I want to get them also on a good pellet or flake.I've tried several times but they either chew and spit or don't bother with it at all.I don't like feeding just bloodworms and brineshrimp.I'd rather a good flake as a staple supplemented with feedings of shrimp(mysis and brine)..bloodworms...pinhead crickets..krill...just an overall good varied diet.How do you get them on just a mainstay of flake/pellet??I've never had this problem with any species of rainbow before.They were all actually hogs when it came to eating...anything and everything.Do I starve them for a while???The only thing that comes from trying to feed them flake/pellet is a tank bottom covered with uneaten food.....aaarg...Any suggestions appreciated...
