Hi all, I got a baby black arowana yesterday at about 3in. I’ve read stories on mfk of black aros eating almost immediately after being placed in the tank but mine hasn’t eaten at all even after a day. Furthermore he sometimes simply sits on the ground without swimming, which is unusual for arowanas. Is this normal or is there something wrong? He’s currently in a 20g growout with a 1in marble goby with a sponge filter. The goby simply sits behind the sponge filter so I don’t imagine he would be a problem. Thanks
