Added a corcea clam from bro evo. It opened up very nicely! Thanks bro.
On a side note, tired adding some grape algae but all died, caused alot of algae to grow, so i had to run some rowaphos with my carbon and also did quite a few water change. The algae seems under control now.
There was also some black spots on my green zoas. Online said could be due to stress. Anyone got any ideas? It started off as a small spot then it started growing. Covering the mouth of the zoas, turned my light down from 100% blue and 60% white, to 80% blue and 60% white.
