No PE but growing like weed

[reefpanda]

As per the title, this colony has no PE even during nighttime, yet it’s growing like a weed. What gives?

PE?

 

[fishface NJ]

pe = polyp extensions

 

[exnisstech]

I have a few pieces that never have PE but grow well. Others have plenty of PE so i just accept that some pieces don't have PE but as long as they look good otherwise I just ignore the lack of PE.

 

[Science/G]

There are a ton of different variables that account for why acropora extend their polyps or not. I wouldn't necessarily go tweaking all sorts of things if the coral looks good.

Does the coral have polyp extension at night?

 

[Science/G]

I have been able to increase PE on some on my corals with the addition of amino acids, specifically Polyplab Polyp Booster. My nitrates are a little on the low side for my liking, so this sort of kills two birds with one stone.

Thanks everybody for the inputs

None at all

PE?

Yeah, hands down my favorite class all through school

I’m not a coralologist but I am not sure that PE is necessarily related 1:1 with coral health. Coral can get food by eating and by photosynthesis, so maybe they’re getting all they need without needing to capture prey.

Acropora in the wild extend their polyps, at least at night, always.

i had this issue...it was white bugs.

 

[willpower]

Agree with Biff, some sort of bug white/red/black. Interesting though I've come to the conclusion that these type of pests are very prevalent in the hobby and maybe can in some cases contribute to a stable tank ecosystem with monitoring and good housekeeping. That being said looks like you need to look into interceptor.

 

[FrugalReeferJon]

A good problem to have, not the lack of PE part but the growing like a weed part.

Yes but that’s because they have a purpose to do so, to feed. From what I recall; It’s not passive to open the polyps, it take energy. There’s a number of reasons to expand the polyp and they’re not all positive ones either, feeding, respiration etc. Crazy wild polyp extension isn’t necessarily good, even if the hobby thinks it is. If the coral had developed to not open the polyps because there’s no gain then it won’t, you’ll have to train it by feeding it or accept that the particular colony doesn’t do it.

I would check for bugs, they’re incredibly hard to see unless your know what you’re looking for and you’d really look for them. Especially the white/black ones, red bugs are easier to spot.

Indeed. For example: can turn if flow in the tank and that will increase polyp extension due to a increased need for respiration.

Ah that might explain it, I have crazy flow in my tank

I’m thinking the same due to my high lighting setup
