My clownfish is a spazz...
He thinks he's Jaws..
He rides the current around the tank night and day..no rest...unless there's food in the stream, then he's sensible and sits at the overflow and porks out after he's done pigging it up in the 'Feron Current'.
Seriously.. is it normal for a fish to be SO active?
(he's new, but very healthy looking and active...mated pair..the mate chills at moon light time..)
Always thought at night time fish chose a spot to kinda chill out in, not roam around (literally) like a shark.. (he rides the current with his dorsal outta the water...does all sorta other wonderful looking things, just concerned...that he's nuts...)
