Tearing blasto?

[Red2143]

My blasto seems to have a tear on the edge and there is something growing on the rock below it. What is it and is this the cause of the issue?

Sorry, but I think it’s aptaisia, which is stinging the blasto. You need to get rid of the aptaisia, it will eventually kill the coral.

Thank you. What's the best way when so close?

Its a pest anemone known as aptasia that can irritate the coral. Best removal:
Using syringe, inject either lemon juice or better yet. . kalkwasser powder mixed with tank water into a paste the consistency of toothpaste and inject into the very center core and it will melt away

Do I have to search them out one by one? This is very small like the size of rice.
