Rank the peskiest soft corals

[damsels are not mean]

there are never invasive mandarins, copperband butterflies, or grandmaster krak zoas. its always 'ugly' stuff like gambusia, snakeheads, pigeons, snakes

i disagree. Sarcothelia looks really cool as a mat. Xenia is awesome when it's under control and so unique. Some of the prettiest macroalgaes are invasive as heck.
