I agonized over the decision when I ordered my custom tank for quite a while. After weighing the pluses and minuses I went with glass. Plus, the acrylic had huge bracing at the top that would've prevented me from putting pieces in I wanted and limited the type of filtration I wanted to use.
Size, short term and moving big tank = acrylic
Long term durability and clarity = glass
Just couldn't deal with all the special care /tools acrylic would need for cleaning. Even leaning against it for maintenance scratches (zippers, buckles, etc). No one I knew recommended acrylic long term although I still wouldn't mind an acrylic smaller tank (say 100 gallons or less). And even now all the old acrylic tanks I see look like milk or dingy.
Then you have catfish and plecos that can leave sucker scratches, be careful cleaning substrate against the walls, on and on. Not saying it can't be done but I was like, meh.
You're also limited with backgrounds for acrylic unless you velcro fabric on. Acrylic does uv fade over time because of a chemistry change so clarity is lost even if you polish it. The material itself does this and it isn't just reliant on sunlight. You can delay it for awhile but that's it.
Have you owned an acrylic tank? If you don’t mind post a pic of a tank you had that’s yellow, post a pic of an acrylic aquarium you have seen that’s yellow or post a picture of any acrylic aquarium that’s yellow
