Not good news.
As you know Friday night the mantis was curled up under the internal filter but looked like it was moving. Saturday morning I didn't see any movement but I left it alone all day in hopes it was just hiding out and being shy. By Saturday evening it was drifting along the bottom of the tank. I tapped it a few times with a prod and no movement. So, I pulled it out and it smelled pretty bad. It definitely was not a molt and was the full mantis. So, I'm assuming it might have died some time Friday night into Saturday morning.
My water parameters were:
Temp: 78
Salinity: 35ppt
pH is 8.01
Ammonia: 0
Nitrite: 0
Nitrate: 5
I even did a copper test even though all my crabs, corals, and anemone would be dead too and it came back as 0.
Not sure what could have caused it to die. I did a drip aclimation for a good 1-2 hours. I have plenty of small blue leg crabs and I guess snails still thriving in the tank along with some macro algae that looks good and not going sexual at all. My zoa's and polyps are doing great.
I did a decent sized water change last night and changed out my carbon after pulling out the G. Smithii just in case it contaminated the tank.
I emailed bluezoo and gave them some pictures of the dead mantis. Should get a reply from them on Monday.
