I bought the proper bulkhead for my aquarium yesterday. It turns out the opening for the bulkhead was 1 3/8" rather than 3/4". I had drilled my tank for the size of the PVC
rather than the bulkhead. I did not know that the bulkhead would be larger.
So, I had to remove all my rock, sand and livestock to my sump and a holding tank. Then I had to re-drill my tank to fit the new bulkhead.
Once I was done, I moved everything back. My red sea star did not make it, and I believe that in the commotion, my condylactis anemone ate my cleaner shrimp (it spit out a claw this morning). I think my cleaner shrimp wasn't going to make it anyway, as i had quite a fit getting him out of the sump and back into the tank, and he squished himself into the pump manifold. He swam away when i put him in the tank, but i never saw him again, except the claw expelled from my anemone this morning.
My 6 line wrasse has gone into hiding in a rock and will not come out. My Zoanthids won't open nor will my xenia. My leather coral is ejecting slime.
Will my tank recover from the trauma? How do I know when a coral is dead and needs to be removed?
