Just finished cycling my new 60gal. Got some live rock, a little algae growth, a few snails and two Talbot Damsels. I put the second damsel in yesterday morning. They were introduced one day apart. This morning I wake up and notice only one damsel. I looked everywhere. There aren’t many rocks I overturned every single one, checked the wave maker, the heater, the inlet and outlet for the canister filter. The thing vanished into thin water. Any ideas?
