Monti cap not extend polyp

[mushy coral]

Im new to SPS coral and got my first monties last week. 2 frags 1 green 1 red and i mounted them on the wall of my tank. The red one at the back with mild flow open its polyp beautifully but the green one doesnt extend any of its polyp. It is at a spot with highflow but not direct. The flow from wavemaker surge up to the surface, crash the upper wall and then curling down to the monti below. Do i have to worry about it not extend polyp and will i have to move it anywhere else?
Tank parameter:
Salinity 1023sg
Kh 8.6
Ca 450
Mg 1350
No3 10
Po4 0.2

SPS don't always extend polyps. If it's new there could be the reason.

I will say though if you have a lot of soft Coral that Could impede the SPS growth.
To get around that, run lots of carbon.

I dont know that SPS dont always extend polyps lol. Thanks alot, i think it could be the toadstool. Ive been moving it around these day to find a new spot for it.

Personally I would leave it alone, it looks fine to me, and one week it not much time for a coral to acclimate to your tank. I don't think you should judge its health or happiness on polyps, that doesn't always matter IMO

I keep lots of LPS and soft corals and most of the time I look for the polyps to see if the coral sick or not so i thought SPS would be the same XD. BTW what sign should i be aware of if the monties arent doing well?

 

[Mr. Mojo Rising]

The green monti grows very quickly, soon you should see a line of new growth all around the coral. If you don't see the line of new growth in maybe 2-4 weeks, that would be a sign that something is wrong. IMO But the coral looks fine to me, its a very healthy color IMO

Finger cross hope it gonna grow soon and spiral upward into layers

Little update on the monties. I moved the green next to the red one on the back of the tank, lower light and bit lower flow. They still in a high indirected flow but these day i notice both of them turn more brown in color and got a slime on the surface. Whats that and what should i do?

That does not look good, almost looks like algae is growing on them.

I would consider a hydrogen peroxide dip.

I have some hydrogen peroxide 3% in hand, how much do I disolve with water to make the solution and how long do i dip them. The green algae grow in my tank quite fast, but i thought that they cannot grow on coral in highflow no?

I refer to this guide when I do any h2o2 dipping:

Peroxide dipping guidelines (for corals)

A while back Justin Credabel published this chart detailing the concentration of hydrogen peroxide appropriate for dipping various genera of corals. I've used these guidelines myself a few times to remove algae from coral frags and it's been quite effective. Justin Credabel's hydrogen...

Thanks but can you tell the type of algae on the monti and how they start growing on them. I pretty sure that they in high flow and low light

I have a very similar monti cap. The thing grows like crazy. I have never seen it with polyps.

I can see polyps in your picture. They're just the same color as the body of the coral. It's good. don't fuss with it.

I circled a few obvious ones.

Yes but thats was when i hadnt moved it next to my red one. I put a little update on this thread so its pop up again. My 2 monties are looking bad and bryanm said that they got algae growing on them and suggest me to do a hydro peroxide dip. I just wondering what kind of algae and how did they grow on monties that at a high flow spot

Look, taking your coral out and dipping it is a last resort type of thing. I've done it to save corals from rtn and such, but never for any other reason than "this thing is gonna die if I don't". My point was that the coral looked fine the first time and you likely shouldn't have messed with it. I don't see any algae growth in your picture, but algae can be controlled... If there IS algae growing on the coral, then it is growing on small spots of exposed skeleton. this can happen just from damage while mounting. You're pinching the coral and pressing its very thin tissue into a hard skeleton. It happens and usually heals up.

My advice would be to let it be and let it rest in some stability to see what happens. If you have algae, work on that. if it's growing that fast on the skeletons its probably diatoms or dinos or cyano... if you don't have that happening anywhere else in your tank, that isn't likely the culprit. But again, all those things can be fixed fairly easily.

corals will also go through changes based on their new environment. If things aren't perfect, they'll usually lose their vibrance and their tissue will brown. This could also be what's happening and would be my guess based on the inconsistent discoloration of the tissue.

Cheers.
