Questions from a Newbie

[Ian]

K so mystery is soled as to whereabouts.....it would seem my little clown has found a place in the return area in the backof my tank....I know i said I looked there but this guy has decided ths space between the plastic liner on the inside of the tank and the exterior(?) wall is the place to be. I only lucked out and saw him swim by the water level windo when I checked iot tonight or I may have gone days thinking it was toast.
Now I have to figure out how to get him outa there....I keep you posted.
