What's your experience with high mortality corals?

[Darkxerox]

So since our club's goal is keeping animals alive, I'm curious if anyone has been able to keep any of these corals alive long term: Trachyphyllia, Wellsophyllia, Homophyllia australis (Aussie scolys), and Heliofungia (long tentacle plate)?

I've noticed a very high mortality rate when looking at tank journals or videos online. I have some hypotheses (mostly light, internal parasite, and flow related) but I wanted to hear what other people think.

What’s long term? Had a trachy a few years once

I had an awesome Heliofungia for three years, but most last 1-1.5 years for me.

I don’t know how long I’ve had it, but I still have this Bleeding Apple Scoly. The earliest post I can find about it is from May 2018.

I'm thinking 1+ years.

@RandyC do you feed it? Also how much PAR?

Never feed it. I might have years ago when I first got it, but definitely not now. Nor for the last few years.

It has varied in the amount of par it’s gotten. Usually never less than 100 and sometimes it might have got 2-250 probably? It’s probably sitting around 125 now.

The scoly I have was in a tank for over a year, and I've had it now for over a year as well. No fish, but I feed lps pellets to acans and scoly 1-2/week.

For the scoly success stories, did you mount them on rocks (angled or flat) or sand? Also did you notice any boring mussels in the skeleton?

No boring mussels that I know of. Also, small rock/skeleton mount, then on the sand bed. Sitting about 1" off the sand. Also mount is at a maybe 30° angle.
