Kris, great additions! Your sump is gigantic! I like it a lot!
I just wanted to make a quick comment on cleaner wrasses.
There have been studies done on wild cleaner wrasses. The myth that they only survive off of parasites and dead tissues from fish is completely false.
Scientists in Hawaii, as well as other locations have caught wild wrasses and euthanized them in order to study their stomach contents. What they found is that a very low percentage of their gut contents were parasites and dead tissues from fish, the rest was typical browsing on plant matter, and plankton, as well as other natural foods they would find on a reef.
My guess as to why they die in captivity is that they are extremely fragile and don't handle shipping all that well. I'm amazed that any fish survive the ordeal they have to go through. Reef to bucket to holding tank. Holding tank into a bag, then into a box and loaded on a plane. They then end up on the west coast usually and go in a distributors tank. They stay there for a shot period of time and are then shipped to a local wholesaler who puts them in their tank, then they go into the tanks at the lfs, then into yours. Pretty crazy. The whole trip they are exposed to numerous pathogens.
Sorry for the side track Kris.
