Hi Im new to marine tanks, I have a ORCA 24g and its been goin for about 10 days now. I found there little plant like things growing out of the LR... are they ok to have in there or should I take em out? Thank you
Some form of Macro algae anyway. As mentioned by Tim, your CUC might decide its a tasty morsel, but if it has some defense, it might continue to grow. Its fine. Let us know how it goes!
