Came home, said hello to the fish, and did a quick count; I was one loach down, and the CO₂ generator had an orange tail …

Seems that one of the loaches had decided it was way cool to get wedged up the back of the gas generator, and couldn’t get back out. I gingerly pulled off the device from the side of the tank, and the loach fluttered off, a little dazed.

No sooner had I put the generator back did another loach zoom up and get jammed. It must’ve been told that you got a “wicked headrush, dude”.

And for this reason, loaches don’t rule the earth.
