What coral is it that you will NEVER add to your reef?

[Alexraptor]

Actinodiscus! Never again! Those monsters spread everywhere and are a nuisance to get rid of.

 

[Stevorino]

Just echoing the GSP/Xenia comments - They just are more work than it's worth to contain.

Dendros/Sun Corals... love them to death but the spot feeding is a pain.

I probably won't do mushrooms again in my new build unless they are high dollar bounces that are worth the PITA to frag and sell.

It’s only one miilllliiioooon dollars!

Fairy Food

Almost mythical acro. While it does exist, I honestly don't know if I'll ever be able to actually frag this thing. Sorry for the tease. ;) Sure if you want to make me a millionaire and become instant lore by all means go right ahead and buy it. I'll probably deliver it personally as well. :)

An expensive one the problem I have is that I have short arms and long pockets

I think you forgot to mention the ones your wife doesn't like.

Had it once many years ago, never again Galaxia. The thin long fishing line like sweeper tentacles are a nightmare.

I'm really surprised at a couple of the answers.
Blue ridge is brown yes but it's a classic reef looking structure.
Gargonians I put in the back of my reef and forget about them. After a couple of years they grow up in there colunm form so they are visible. If they were the non-photosynthetic type, I can see why someone wouldn't like them.

Anyway, for me, it's the blue clove polyps. Wish I knew how bad they were before I added them. They are pretty much under control with a few stragglers living on the bottom glass. I'll deal with them shortly when I get some time.

Pinkish anthelia. Not even Roundup kills them ;/

 

[Slicktop]

Green mushrooms, they will spread and cover everything ... then sting any other corals near them to death. Had to remove 90% of my rock and replace to stop the spread. I still see babies now and then and needless to say they are removed quickly.

 

[Waters]

I will not add any montis again....had to tear down my last tank and start over due to overgrown montis. They grow too fast and encrust everything lol.

 

[David Gaskins]

Green Mushrooms. Must worse than Xenia in my opinion, and on the same level as Aptasia for spreading and coral aggressions.

Zoas & Acans! I can grow any type of coral in my tank. LPS, SPS, softies but those two types of corals always die on me.

This is a great post. Thanks everyone for helping me avoid a huge future mistake! Haha

Keep in mind, a lot of these are personal preference. Not every coral listed here is a mistake in every tank. As long as you do your research and figure out if a particular coral will work well with your tank and your plans, go for it!

I hate half of the corals listed here and love the other half.

#1.Blue!!!Clove!!!Polyps!!! They are by far the worst invasive coral ever!
#2. Rhodactis mushrooms. They too spread and are difficult to get off of live rock!

Thumbs up for Tyree neon green toadstool leather. Mine a year plus ago. I still have a healthy frag. Beautiful coral!

Beautiful coral for sure!!!
