I'm really bored right now and looking at all these cleanest fish, biggest fish thread and was just wondering what are the smallest fish? Fresh and saltwater?
if we are talking strictly gills and tails, i would trust oddball. but if you wanna know the smallest SW with a little bit of open mindedness its phytoplankton
Not sure. The smallest I've kept is a colony of Catalina gobys (Lythrypnus dalli) in a small chilled tank. References say they grow anywhere from 1.5" to 2". My 3 year old colony never passed the 1" mark.
