Weird growth

[Cole nelson]

So I have an all coral tank as of right now and out of the blue I noticed a strange growth behind my frogspawn. I don’t know weather this is dangerous or if it is some sort of coral. It is colored purple/blue with orange dots

Hard to tell from the pic..... look up sea squirt. They often have crazy colors and polka dots.
