Update again... no pictures.
One of the 4 chromis is MIA. Haven't seen him for a couple of days, and I am fearful that he is crab food. When they were all introduced to the tank, they all schooled for a day, and then the single one went off on its own for a few days and then disappeared. They all looked fine, and the other 3 are doing wonderfully. It was odd. Maybe there just wasn't something right about him.
Then, yesterday, I went to feed and the watchmen goby didn't come out of his home. Everyday when I feed he comes out and waits for some food to come towards the bottom and eats it. We found him last night when going on an aptaisa hunting excursion, and he was dead... in his home.
A bad day.
The weird thing is, everything else in the tank looks great and I will talk more about that later. I hope something isn't in there killing these things. As posted earlier we took a big red eyed reef crab HH out and a mantis out, but I am starting to think that there is something else in there.
I suppose it is possible that the watchmen starved, since the other fish are so much faster at catching food floating in the column, but he seemed to get a decent amount.
Before all of this drama though, we made a few more purchases. I don't have pictures now, but wanted to update. We picked up a purple ricordia, and a copperbanded. I know its still a bit early for the copperbanded butterfly, but we noticed a field of aptasia in the tank a few days ago and needed some help killing this stuff. The trusted LFS stated that they have had him about a month and a half and was eating mysis regularly. He looked good, so we got him at a good price.
This morning, before lights on, I was looking in the tank and he was already out of the cave he was hiding in moving around the rockwork just looking at it. He has been doing that since being introduced to the tank. Haven't seen him pick at anything except a few HH feather dusters. I am excited to get home today and see how he is doing all settled in.
KH continues to be a bit of a problem. We have been dosing Kalkwasser in our RO top off and I think that might be contributing to a KH which moves between 4-7 Dkh. The LFS suggested Reef Builder supplement to try and balance the KH with our high Calcium of 520-540. He told us to stop dosing Calcium until we see KH come up and Calcium start to drop. Thoughts?
Thats it for now, everybody else is happy and healthy. Sad day with one KIA and one MIA however.
