Im no expert but we have all in all 10 datnoids
I refuse to feed feeders to any of my fish so we just offered a variety of foods as we feed the Arowanas and rays
We found the Indo's were first ones to break the hunger strike and were eating about two weeks later and some eat frozen but two of them only take pellets which is ok
We had 3 NTT's that were already about 15cm when they arrived and these three musketeers starved themselves for about five months....
Got to a point that i was almost in tears
One night out of the blue, one came darting for shrimp and then all three started eating
Today they eat anything... prawn, mussel, sardine, white bait, tilapia, pangassius... except pellets
