No PE on acroporas

[Dudefish82]

Hello Reefers!

This is my first post here,
I recently moved to SPS in the past few months. Started with montiporas, which were growing pretty well. So I started with some acros, tri color milli, green slimer, blue milli, garf bonsai and unknown acro. I noticed the tri color milli turned green and the unknown acro turned brown and now its also turning into green. Ive had these corals for around 2 months, and after 1 month all the PE dissapeared on the acros except for the green slimer. They are encrusting very slowly but no PE.
Tank parameters:
alkalinity: 8.7 dkh
calcium: 430 ppm
magnesium: 1260 ppm
nitrates: 10 ppm
phosphates: 0.15
I have a 3500 lph wavemaker for flow set to random flow as well as the 1000lph return pump. The tank is only 25 gallon and is 1 year old.
live stock:
2x clownfish
1x target mandarin
1x elongate dottyback
1x wrasse
1x coral beauty (havent noticed nipping)
thanks in advance

Some Acropora types show PE more than others. With that said, a Dwarf Angel nipping can be very subtle.
When I notices diminished PE I check for Red Bugs and other mite types.

Whats the lighting? Could be under lit that's why youre seeing the colors turn green. As for PE I would not have high expectations with an angel in the tank.

Typically I see acros turn green when they do not get enough light. As for your PE, that can be related to light but I would suspect that Angel is nipping.

welcome to the world of acro's and the ensuing madness of trying to get PE lol. So much as a fart will make it go away.

start with basics, the magic 3-
good flow
good light
stability

really understand and know what the magic 3 are and what it means to be good with all 3 of those. If those 3 are truly good, you can move to the next step and start looking at trace, bugs, etc.

Acros and zoa's are kind of opposites in regards to lighting and flow requirements, seeing them right beside each other makes me wonder if the light/flow are enough for the acro's.

I have acros in the same tank with a lot of pe, some pe, little to no pe. I've started ignoring pe since they're all growing and colors are good for the most part. If I have a lot of pe great, if not meh.

Did you get all of the acros from the same source? If not, could be a pest introduced by one of the sources.

Not from the same source. I thought that might be the case too or the angel nipping

I have had dwarf Angels before that were buggers for nipping Acro polyps, but not if you were watching. Seriously. If you were in sight of the tank it wouldn’t touch them… I snuck in with a black sheet draped over me and the room lights switched off, and sat and watched as the Dwarf Angel picked every Acro polyp it could find… I’ve had a cherub Angel, Flame and coral beauty and they all did it. Never again!

Welcome to Reef2Reef fellow Aussie!

I have a similar issue in my tank, but lots of PE at night - i would suggest that the corals can sense that there is an Angel in the tank, so its a natural defence mechanism.

 

[Dudefish82]

You guys were right! It was the angel. After getting rid of him the polyps are returning slowly but surely!

I have a dwarf angel in my tank with lots of PE -- I really think it just depends on the fish
