Moorish Idol lands in Calgary

[Samw]

Awesome Deb. Remember my story, I nearly lost her when I unplugged the skimmer one night. The next morning, it lied flat on the sandbed and the only movement was the heavily gasping gills (gasping for oxygen). It recovered only after I plugged the skimmer back in. If I woke up that day an hour later, it would have died "mysteriously". Other fish can survive on regular oxygen levels but the Idol needs more than other fish. They need more than tangs. Powerfilters and powerheads that ripple the water is not enough. They need big waves crashing or artificial aeration (skimmer, airstones) or they'll quickly suffocate regardless of the size of the tank.

EDIT: My tank looks so empty.
