I just picked up 2 of these, Green Band Gobies, they are about 2-2.5 centimeters.

The QT they are in has a very small powerhead aimed straight at the surface. 1 week so far so good but my display has a small powerhead too.

I've been keeping small fish in small aquariums for awhile now but these guys are really small and I plan on getting a yasha goby next..

So I am considering upping the return pump flow and getting a dual return nozzle but I'd like to know if anyone thinks it would be unnecessary.
