A Polychaete Word of Caution

[daniella3d]

I have a lot of these worms and they never affected my zoanthids. But I did have problem of zoanthids shrinking to nothing and it was caused by Seachem phosphate remover aluminium based. The shrinking stopped when I removed that stuff although some polyp have yet to recover and they are still tiny bitty but they have stop the shrinking at least.
