I recently got a baby black arowana in maybe 4 days ago? and I have him in a 20 gallon long because I feel like my 300 gallon is too big, and has bigger fish that could eat him , anyways, I've tried feeding blood worms, brine shrimp, live meal worms , baby guppies, flakes and pellets, and nothing seems to be getting him to eat, I have noticed his tail is slightly bent , I was thinking due to stress from shipping and being moved into another tank, I currently have a UNS filter in the tank , a heater set to about 78 degrees F , and was wondering if this is normal for a wild caught baby arowana to barely be eating in his new tank? also i would love for him to start eating so any idea on how to do this?
