Same problem with the System Six.  The bulb to too far
forward and everything in back leans a-way towards the
front.  It's very difficult to scape.  

Size is difficult too for fish that have any tendency
towards territoriality.  The minimum territory takes up
most of the tank volume.

Part of the problem is that the bulb is place forward of
the ballast.  You could solve that by removing the ballast
and light assembly and replacing it with a 13 watt PC,
keeping the ballast remote.  The filter will still block
light from the higher reaches of the rear of the tank, but
it might still be an improvement on a 3 gallon.

Water is clear, stable and fish seem happy.

If only the weren't bow-fronts, you could just put the hood
on backwards :-(

There's quite of few little hobby pumps around, including
ones for electric train setups -- which is how Eheim got
started in the water pump & filter business, BTW.

I've found the little Rios to be rather durable.  Most
little pumps are expected to be submerged to provide
adequate cooling.   What about a little back filter
(a.k.a., power filter) like a Hagen Clear Mini?  All that
goes in the tank is the siphon tube and that can be very
short, if you want.  You don't have to use any media if
don't want to, but a back filter keeps the pump out of the

Good Luck,
