Do NSA’s create unhappy fish? Currently have the rock wall look, I like it but have reports this is flow restricting and also coral placement restrictions which I can understand both completely. Was planning on using 35 lb new dry rock to do NSA and put it in the big DT with much of the existing live rock down in a 40g breeder for the refugium whenever I get around to it.

dont want to make sad fish in my tank as happy fish are the only ones allowed. What’s experience with NSA and if poor experience what is good alternative open to all suggestions

no corals attached to the rock yet but bonus points if it includes keeping the rock wet enough for the bacteria to stay alive
 
Id say that NSA can make unhappy fish if you make it so there are little to no hides. Make some arches, grow coral that plates, take some rock rubble and glue it to some pvc couplers for sand bed fish and inverts to hide in. Its totally doable.

I can’t picture the PVC thing but am very interested, can you explain to a dummy
 
Depends on what you do with it...
I have the following fish in my tank.
One spot foxface
Magnificent foxface
Scopas tang
Convict tang
Blue throat trigger
4 bangaii Cardinalfish
A pair of 6 line wrasse
2 springeri damsels
A single misfit oscellaris clown
2 yellow Watchman gobies

I have no aggression and all my fish are always out. My tank has been set up 8 months. I just added a new peice of scape to the left side of the tank. My beautiful wife built it.

When an NSA is built right and the coral grows in and are well placed. You should have no problem.

Excuse the dirty glass being cleaned tomorrow.

This is a controversial one... So, assigning emotions like "happy" or "unhappy" to fish isn't the way to view this. Because none of us are fish, or have been in the past, we can't say if they feel emotions in the same way that we do. However, we do know that fish can feel stress. I believe that the conditions provided by NSA can cause stress. Sterile, open, and relatively unnatural. While the reef at large has many arches, overhangs, and spires that are somewhat NSA like, our fish are tiny. They don't see those formations, they just see a bunch of crevices and small holes on the wild reef. I think that the best scape is one with many small crevices that fish can jam themselves into. However, that isn't to say that NSA is all bad. If enough small caves are provided, and the mandatory low stocking levels are respected, it can be done. However, it would make your life and the fish's lives easier to just have a pile, or some islands. I hope that this helps!

NSA can still have lots of places to hide. For example you can get some get some ‘stick’ shaped rock pieces and pink Marco cement and make a few teepee type structures with lost of nooks and crannies for fish to dart into and through.

This is NSA done right, with the future coral and current fish habitat in mind from the beginning.
 
While a decent selling tool and fun project, NSA is a poor trend that will disappear in time. Even BRS has moved onto Habitat based NSA after they realized how stressful it is on the fish.

Your corals are your aquascape. Pile the rocks in a safe way with some openings in and out. Think of corals that can go in each place and what colony growth pattern you'll see down the road. The fish will find the safe spots to hide and sleep and you'll have a healthier ecosystem in the end.

I find islands/bommies are the best way to go.

Take a pvc coupler, and some rock. Break the rock into some rubble, then glue it to the pvc. Now you got a cave that you can put anywhere you like and it looks natural. Bonus is you dont have to worry about anyone collapsing it and it can be moved if need be.
 
I have NSA, and the fish seem to love it. They have tons of room for swimming, and because 95% of my rocks are lifted, they have lots of places to hide under.

They actually seem to prefer the more open areas of the tank. Except for like the blue tang, who likes to find places to wedge between. The place I figured would be a good spot doesn't get used at all, go figure.

Even in the areas of my tank where it looks like they aren't lifted due to the sand, it's actually lifted and gobys, and things are able to easily make homes under the rocks.

I can see where just using minimal amounts of rocks could cause issue. But if you are lifting the rocks giving them big ledges and things to hide under all over the place, I don't see the issue.

I guess my fish are like:

Can u post a pic? I think where I put people off was when I said “minimal rock work in DT” I will have to readjust that thought process and make sure if NSA then there is still ample rockwork even if it is not piled up

Yeah, but it's really hard to get a sense of what's really going on with pics to be honest.

Here's the right side of my tank. This is the favorite side of the fish. It's 1 big rock, but you can see the naso under the ledge of the left side. All of that to the left is elevated. That is the #1 spot for the fish.

On the right side of the rock, it's not so easy to tell, but there is an arm that goes out a little to the right, but then it circles around all the way to the front. On the backside there is a little overhang, and that's the mimic tangs favorite spot. There is also a big split in that area on the underside, which is where the blue tang likes to fit, but he has a few other places also and I think he's about outgrown that spot now.

I actually hate the coral on this rock, but that's another story. I want to kill all the zoa/paly really. This pic is like 6 months old, but the rock is much more covered now. The green zoas on the right side of that arm have covered it completely, even the bottom side.

And this is the left side. There are 2 main rocks here. And you can't see them in the pic, but lots of caves. And entire area between the 2 rocks that is even more covered now due to the chalice. The entire front left to arm there is raised, I didn't really need the pillar there next to the sixline, but added it just in case. That arms goes all the way over to the candy cane, which is on the right end of the arm. The hammer is on a rock in the middle. Behind that arm is the 2nd rock, it's pretty small, you can see the duncan sticking out to the right a little, but it's actually in front of a cave that goes through that rock. Smaller fish only.

The area where the watchman goby is is also lifted. It doesn't look like it because the sand goes up to the rock, but it's a big area under there for those types. Peppermint shrimp hangs upside down right next to the goby. Also the entire rock does a front to back type slope, so on the backside it's a bit of an overhang. Sailfin is the only one who prefers this side of the tank, but only for sleeping. However, the blue tang is spending more time over here lately as he gets bigger, likes the area behind the sixline, between those rocks(front to back where you can't see, not the open area to the left).

And in the middle you can see in both. That's the diamond goby's home, he puts alot of the sand on top of that one rock. Usually he makes a hole in the back to come in and out, but I see him putting a hole in the front from time to time as well. I figure he's letting flow go through, like opening the windows.

I have no idea where the wrasse go at night. The smaller fish have tons of places to go, it's the tangs I worried about the most.

Of course, the biggest hack is the use of cardinals, who like the open space.
