Disappearing Kribensis

[Genesis]

ive recently moved most of my fish into my new 50gal, i cant remember how many kribs i put into it, i originally had 3, now i can only see 2 in my 50gal at any one time, and there is nothing left in my 15gal except a filter, could it have got stuck in there? the filter is a Trio 2000. or could it just be hiding somewhere in my 50gal? though ive looked for ages

please help as im quite worried for it

I would check the filter in the 15gal just to make sure, he could be hiding in the main tank, with the stress of the move over, hope you find him, good luck.
