Help an sps noob - some are great, others not so much.

[Kongar]

Why would some sps do great and others not so much? I recently got a battlebox and I have two similar pieces next to each other. One is thriving - crazy polyp extension and I can see growth in just a few short weeks. Right nextdoor to it is another acro that doesn’t have any extension and today I noticed one of the branches is bleaching/fading in the middle of the stalk. Not at the tips, not at the bottom. Same flow, same light, I don’t get it.

They’ve only been in there a couple of weeks, could they still be adjusting? I’m hesitant to move the stressed one, but something is telling me it’s just not happy. Is it common to lose the odd acro in a tank where others are doing well? With lps, when one isn’t happy, they all aren’t happy.

What kind of flow?

What kind of flow?

Same flow for both - high. Polyps get blown one way and then a variable flow nozzle directly blows on it from the other direction every second or so. Or I should say, the polyps on the one that seems to be happy blow around, the other isn’t too happy and there’s no polyps.

Might take the stressed one out of direct flow. That could be adding to the stress.
