Does anyone know what their behavior in the wild is? Ambush hunter? Cruising predator? Maybe they lay around when not actively seeking a feed
I have a vague recollection of seeing marbled gar for sale here. From memory in a similar price range at that size
Common gar behaviour. You’ll see them floating at the top surface like a log, not moving much and letting the currents take them. You may also see them, similar in this case, resting at the bottom, until they require a gulp of air where they will swim up.
They are ambush predators; meaning they’ll wait for prey to swim close to them before they strike. They aren’t actively hunting for prey such as arowanas or dorados. The larger, older gars tend to rest at the bottom. Younger gars you will see swimming more and at the surface.
The marble gar in the photo, I’m eyeballing around 20”? Seems like an okay price for its size in the US.
