TheProject,
The hose is the airhose that leads to the castle. The castle has bubbles that come out of the tower (though you can't see them in the pic because my air pump was defective.. got a new one today though so I'll have more pics in the future). I didn't have enough tubing so I had to do it like that. Bought some more tubing today. Going to run it down the wall of the tank next to the left plant & UGF tube and then run it under the gravel to the castle. Poof... no more tube.
KEL,
29 gallons... freshwater. I'm a newbie so I don't want to fool with saltwater or live plants. =)
Boach,
Gonna get myself a common pleco aka "sucker fish" in about a month or two when the algae develops.
OMEGA,
Enigma, eh? =)
