Hahaha "NEED" sure
Until I see proof that feeders is better than a variety of pellets + mp I still think that NO fish NEEDS live food. So i'm guessing most of the keepers on MFK who feed their fish pellets/mp etc. are all doing it wrong ? as they need feeders for growth and health.
Predator fish does not mean they NEED live food.
That's like saying humans will not live healthily if they don't eat meat. Ignorant.
As for the tankmates? they are all same size (and slightly smaller than the gar), I did not just throw them all and leave it, I had alternative plans for the Gars if there was any problems with aggression. The reason why they took pellets so quick? Because other tankmates are dashing for the pellets letting the Gars know that the pellets IS food and getting them going.
You could say it's luck but I kept the characin's in there for a reason. And so far the whole tank is getting along fine, no nipped fins or any dominance at all.
