Zoas are dying, parameters are solid. Saw this guy on my Zombies and have no clue what this is! Anybody know and could this be the zoa killing culprit?!
Amphipod, I always try to keep these guys out of my tank, or at least control their population. I know reefers have differing views on these guys, but IME even if they aren’t the cause of a coral being agitated and closed up, their feeding frenzy on injured or damaged coral tissue can cause an already stressed coral to decline further.
