A watchman would be nice, and the yellow color would look great next to the orange and blues! And a 6-line would be fun. In fact, the 6-line has been on my shortlist, don't know why I forgot to list him.

And I loved my tiny red cap goby, I was heartbroken when brooklynella wiped out all my fish in the beginning.
I need to look at the tube-fuge again, it's definitely a great idea. Although, being married to a plumber can make it even _harder_ to get certain projects done!

But is there a decent way to feed an exterior
fuge without trashing the stock lid? I've thought about just buying a standard tank and adding extras like a
HOB fuge, but I like the looks of the BioCube and it does seem cheaper overall. I definitely like the tight lid since several of the fish I like are jumpers.
So, how many fish of this small, peaceful size can I keep happy in approx 30 gallons?
