Hi!!! I wanted to report an update to all!
HURRAAY, IT STARTED TO EAT!!!!!!!
Just like 3 hours ago,I offered him a live guppy. It was already alerted by the opening of the enclosure,so, with slow movements I dropped the fish just a couple of cm in front of him. He started to smell it a few times with the tongue,and continued staring at it for some time, like thinking "so... now what am I supposed to do with THIS??" but then got closer and started touching it with the nose and Ta-Daah, no more guppy! I'm so happy!!! ^^ Then he stared to look around for more! but I only fed him one for today, don't want to charge too much his stomach.
Oh and Dan,I checked, and it seems indeed that I have a Pulchrilatus! Thank you!
And Rhea, I bougth him 2 weeks ago
