cool I just got one too, he's about 3 inches. my jardini is about 5 inches, i hiope he doesn't decide to eat the ghost knife when he gets bigger! do the ghost knifes ever actually find food? i had to manually put freeze dried bloodworms in his tube, and it was cool seeing him suck it up with his tiny mouth. but, i also got sinking granulars that the guy at the store said the fish would eat. so far, the granulars hit the ground and blend in with the rocks. will he ever find them or will my pleco get to them first?
