Which corals would you never (again) put into your tank?

How bad are the palythoa grandis?
Are they as bad as captain jerks?

I picked up a frag last week and I'm wondering if I should be concerned over them or not?

I am not keeping any paly's or zoas in my new systems because we have a small child in the house and I don't want to play that game of are they or aren't they the toxic ones.

Depending on the system, I might consider any monti, soft coral, birdsnest, stylo, or anything else that can spawn unwantedly or be difficult to remove/kill in the tank.

Mine are cloves, and xenia. Never again, not even once. Pretty much everything else can be "fixed" by smearing epoxy and letting it cure over the coral, killing it.

Zoas. Honestly they grow so fast and are so aggressive

The only zoas that don't grow fast or the ones you want to it seems. I have a candy apple red that's been a single polyp for almost 2 years.

That’s because we do this too much

This. Zoa gardens are bullshit. One will eventually overtake the others

This is my experience so far as well.

But zoas don’t seem to irritate or harm the non-zoa corals nearby? I have some touching various things and don’t seem to kill or do any damage.

Unlike mushrooms. I like mushrooms but they are mean too.

Nirvana Poly. I got one at the coral swap at the beginning of may and it is growing crazy fast. Just about ready to pull it out. Very scary fast growth.

To minimize its deadly tentacles effect, I put it under the circulation pump where the flow is upward; therefore, all the tentacles flow upward as well.

Xenia is my headache. I try to grow/content them in the sump right now but they still pop up in the rocks in DT. I have to wait for them to grow then rip/pull them out with tweezer.
