Just focus on the survivors, maybe expand on different varieties of those species.Looks like we have no problem with certain corals, and then some do amazing for months, then one day come home and they're died or bailing.
Looks like we're gonna keep track of which do best for us and keep those. So far they include
Toadstools
Gsp
Zoas/polyps
Chalice
Stylophora
Certain encrusting corals (leptos)
Anenomes
Favia
Euphylia have done well for us until we moved to the 125, then we started to have issues. We've lost 2 of our frogs, 3 torches, and a hammer. Just odd how they die out of nowhere.
The past couple of years my tank was back on track, new zoa's, hammers, brains, cyphastrea all growing well, even a couple of sps doing ok.
I took a couple extended vacations this year, both times with good house sitters, but had some mishaps or shifts in my routine that likely caused some mortality of corals I thought were "bulletproof".
