my 14 inch only took feeders when i got him. so i fed him a lot of that for a week. after that, basically put whatever you want him to eat in the tank. try and try again. also helps if you have tankmates that eat the same food as the tiger. in this case, i was feeding floating pellets to my aro and prochi. took over a month before the tiger ate the pellets. hes now hooked onto pellets but wont take prawn! lol
When I first got mine at 1.5 inches i just dropped some Azoo Aro sticks in with a cube a blood worms and they fell for it ! Must be easier when they are still juvies.
