A busy afternoon!

[mrhasan]

Alright so suddenly, at the afternoon, I noticed that one of the zoa frag's rock (small) got 3 AEPTASIA!!!! I was like OMG. I took it out at once, and dipped the bottom of the rock in lemon juice leaving the top (with zoa) unexposed to the juice. The I washed the bottom with boiled water, then zapped it with a lighter and then washed it in saltwater before putting into the tank. I hope those buggers don't come back :@

Some sort of worms also came out during this treatment:



Does anyone got any ID for this?

Alongside, I also notice tiny tiny hydroids on my tank's glass that looks like these:



What should I do????
