Looks like not many were not agreeing with the alleged article given all the comments in response to his post. This is not something I would personally give much weight being a single source. I would expect something baring that type of claimed to be found/reported in multiple places. I don't know enough to honestly say true or false either way. Just my neutral amateur assement on his reported unverfiable article he said he encountered.I came across this that I thought was interesting: https://www.ultimatereef.net/threads/who-keeps-multiple-gonis.859807/#post-8137172
"Goniopora corals should not be kept in a mixed reef garden. They are aggressive and will sting nearby corals. It is not wise to have more than one species of Goniopora in the same tank since that species will release a bio-active chemical that is toxic to other species of Goniopora."
I know goniopora and bernardpora have sweeper tentacles, but didn't know that they use chemical warfare like an anemone. There is no link to the article that person is referring to, so who knows?
That could be the red one I had. I have some to @under_water_ninja when I broke stuff down a couple years agoI think gonis are hit or miss depending on the species. I've had some thrive, and some wither away, all in the same tank. Here's a vid showing 5 I have now. 3 are growing (the red one is a couple years old and was a frag from @under_water_ninja ), and 2 are mostly just hanging in there.
