polyp extension

I've been battling aiptasia in my acro-dominated tank, which is just around 5 months old. I have ~a dozen sps frags, and a pair of rainbow acans. Several of the older acro frags are starting to encrust onto the rock or at least over the frag plug, and the acans have dropped several heads. The...

Hi everyone. I guess advise needed however I’ve pretty much given up on this frag, that said keen to learn for the future. This frag did fine in the tank for a while although no polyp extension at all then it started receding. However recently it has started extending very nicely but still...

I've been slowly acclimating my new acropora frags to my tank - mainly the lighting, bringing the frags up slowly from the bottom of the tank to their new positions. I haven't seen any of the polyps extend during this process. I'm new to acropora, though I know about their flow and lighting...

Hey, so I'm new to keeping saltwater, and I have a gorgonian coral who won't open up, I dropped it in on Tuesday, (the 9th) along with another coral (a spiny gorgonian). The other is super happy and has all it's polyps out so i'm not sure if this one is just being finicky or what? It's next to...

Hello all! Came back after a short trip to find my goni not extending fully. It used extend at least 3-4 inches. Also, seeing some kind of dark staining on the polyps. Does anyone know what's going on with him? :( The tank lighting is on Auto. There is also an ATO / skimmer. Rest of the corals...

The polyp extension amazing. Just wanted to share this. Comment with your styloconiella coral I dragged this twice so far. I’ll continue to frag this one. As I have others and seen other stylo but never seen polyps put out like brooms

I’m looking the way on polyp extension, I try amino it can help on polyp extension. But meanwhile it will raise a lot in No3. As currently my tank parameter wasn’t in stable status, I can’t do heavy import and export. Every time I using the amino, it take some period to lower my No3. And my no3...

Hey everyone, i’m making this thread to show off some of my acropora i’m growing, first i’d like to start with this RR Dragon Fruit, the rainbow polyps are truly unique!

So I have had this coral for over a year, and this frag in a branch from its original colony. I was doing ok for 2~3 months, and suddenly it stops growing and I can observe zero polyp extension even at night time. It does keep encrusting on the rock as of now, and start to show some fluorescent...

IDK what coral this is but the polyp extension has been super great and wonder if it will explode even more. I’m thinking it’s a stylo but haven’t found any close to this coloration. purple with blue rings and yellow polyps. Would like to frag this as well

Hello. This is my rainbowloom acro. I had it for six months now. It was fluffy and happy a month before. Recently, the polyp is not open anymore but it still fully extend. The polyp is not fluffy and soft anymore it looks kind stiff. I also noticed the skin is not that smooth anymore, it's kind...

So this is my Green BTA, been in the tank for about 2 months. Always had great extension and was a perfect until about 2 weeks ago and now will not extend tentacles. Below is my Red BTA, another beautiful specimen on the same rock about 6 inches away and could not be happier. Any ideas what’s...

I have one acro in my 10 month old mixed reef. It’s an orange tipped staghorn I got almost 3 months ago. One side is an unbelievably nice green with great polyp extension. However, the other side is an almost brown color with very limited polyp extension. It’s been like this for almost the...

Hi there, i have trouble find the issue with this acro that have never had PE in 1 month and a half, here some pics after the first week, i have at that time dipped in ReVive 5 minutes and the glueled on a new plug (at night with a white light): This is from couples of days ago (hard to...

Hey everyone, just added my Devils hand to the tank yesterday after dipping it in revive. I haven’t seen full polyp extensions, most of the small polyps are still not open. It is now day two. Is it about to shed first since it’s in a new tank? He’s placed in medium flow and light. thanks!

Hey fellow reefers, I have a waterbox 20, mixed reef with some acropora colonies on the top part of the tank. Before I start my question These are the parameters KH 8.9 Salinity 1.026 Cal 440 Mag 1300 Phos 0.03 Nitrate 5-10 Ammonia 0 Nitrite 0 I run one AI prime HD 16 at 7 inch on top of the...

my stylo has grown like crazy since I got it but has weird polyp extension recently. It looks like only the tips are getting polyp extension and I can’t figure out why.

Hey R2R! I purchased an awesome rainbow monti on 6/8 from my LFS, and have a question about how to get the best PE. The coral overall seems to be fine, and has great PE at night and doesn't seem to be bleaching/receding. It's still on the sand bed since I'm letting it acclimate. However, the...

Hello once again everyone, I was recently looking at some pictures of others tanks and have seen that some have crazy polyp extension with their LPS, the feeding tentacles, and then others have little to none at all during the day. I am one of the latter, during the day there is very little to...

I will give you a hint, G**** C***** C****

I refilled my calcium container and left the pump on while clearing the line. Oops. Rise from 420ppm to 470ppm. I started to notice my polyp extension on a few of my acros was pitiful. Before the rise the polyps looked like they might pop off the coral. Now they are barely sticking out...

Sorry if its hard to see. This is a 7.5g nano. The tank is VERY new, like a month old? ive been testing religiously every day and within the first week i had zero ammonia and 20 ppm nitrate. continued testing until now, my parameters are: ammonia: 0 nitrite: 0 nitrate: 5ppm (cant get it lower...
