Don't QT Rabbitfish?

[Enigma]

This guy was ramming into the glass in the QT. It was actually quite alarming. It would happen when the tank light was on and the bathroom light was off, or vice versa. Hubby kept forgetting this, and kept turning the bathroom light off. He'd swim very erratically at times, too. He wound up so worn out from ripping around the tank that he wound up stuck to the canister filter inlet.

Hand feeding? Nope. Lol. I'll let him settle first.
