So that makes 3 total bartlett's anthias that have now 'disappeared' in my tank, got another on Saturday and haven't seen him in my tank since I put him in and he slid into the rockwork.

The leopard wrasse that I got on Saturday as well buried himself, but I'm not too worried about him, yet and I am patting myself on the back resisting the temptation to dig him out/unbury him (I know where he went into the sand at) to make sure he's still alive -- I don't want to stress him out more ... I know they can remain buried for awhile but this one was swimming around @ RP for awhile and doing good, so I'm hoping he makes the adjustment.

But, I can't figure out what is going on.

The fish that -have- survived are fish that I acclimated straight in the bag, my two clownfish & orange spot goby. After that, I started using a 3 gallon bucket. This is a bucket I bought specifically for tank use, and I use it to do my water changes, and filter sock changes. I am using a slow-drip method to acclimate the fish, 1-2 drops per second, for about 40 minutes until water volume is about doubled. I have lights off in the room, and turn lights off in the tank. Water parameters are all good. I know that fish can be finicky, but it's not just the cash loss for me - I hate being responsible for something that awesome dying, too ...

Not sure what, if anything I'm doing wrong, or if I'm just having bad luck with the Anthias ... this last I got had been at RP for well over a week and was doing great. The other two I chalked up to stress from being acclimated/moved so much in a short period of time.

Any ideas/suggestions? Should I let them acclimate for an hour+? Could the fact I have a bit of trouble catching them with a square net in a round bucket be part of it? Should I get a acclimation only bucket?
