Cons of using PVC?

[NinnJinn]

When I setup my 125gallon Aquascape 5 months ago, I basically took my 2 biggest dry rocks and put them in the back corners of the tank and then started making "layers" left to right until I ran out of my 100lbs of dry rock.

I currently have my first batch of fish in my 29gallon QT. To have hiding spots, I placed several T pvc connectors in for the fish to hide in. Now that they are getting comfortable they just swim through them constantly.

This got me thinking.... with 6ft of viewing in the DT, I really do not have any "tunnels" or actual "hiding" places for the fish with my LR. The aquascape is basically just a layered wall.

What about placing 5 or 6 3" PVC T connectors in the DT and rebuilding the live rock over and around them?

That way the fish can swim through them and also have plenty of places to hide?

I bought some Artificial corals etc, So I was planning on redoing my aquascape anyways.

No cons at all, I made a couple that I epoxied some rubble rock to. My marine betta loved his home of black abs piping. Same for my peacock mantis that had a labyrinth of white PVC pipes under the sand

Nothing wrong but just looks unnatural IMO. If you're going to rearrange all the rocks why not just rearrange them so that there are openings for fish to swim through? Yes they're comfortable with the PVC but they'll quickly get comfortable with the openings in the rock too. All my fish were happily exploring the rocks the very next morning out of QT. Even fish that swims a lot and like the open space like tangs still love swimming in and out of the rock work.

I say re-do your rockwork with hiding places.

As was told to me when I did my first rock work job....think tripods. That is, put down three rocks and now place a large rock on top. Continue making this open walled rockscape.
