Just picked an XL Jardini yesterday, but he has not been eating. He's very active in terms of swimming around, but hasn't eaten a thing. I tried pellets, shrimp, feeders. He just swims right past it without a look.
I have moon lights that I set overnight on my LEDs. Maybe when I set them overnight he will start chowing down. My XL silver arowana in my other tank is a beast, tries to bite through my net when I put feeders in and devours anything I set in there, from pellets to flake.
Try not to give the jar feeders as its like crack to them (very difficult to get them off ) plus it promotes aggression IMO which limits tankmates if any , good luck with him I'm sure he'll eat within a few days , any pics ?
