Just got a black Arowana. Have had him almost two weeks and won't eat. He's in a 180. I've tries krill, shrimp, earth worms, pellets and crickets. Any ideas??? Also he's about 12".
Depends on his size. Guppies will work, rosies too if your afraid of goldfish or comets. I like guppies the best. They are the cheapest by far, and easy to find.
my 6" silver wont touch black worms. They just sink to the bottom. I put a few dozen guppies in there and it was like fish porn. He was on them like a cheap suit. He couldnt look away.
Just continue with what you have been trying. If the aro is wild caught it could take awhile. Mine took about 4 weeks to eat on a regular basis. It is big enough that it can go for a very long time without eating.
Are there other fish in the tank? Also adding floating plants will help the aro feel more secure.
