IMPORTANT GUIDANCE
For aquarium items, PETG is my first choice, especially with your Creator 5 Pro.
It’s a much better fit than standard PLA for parts that will stay submerged long-term.
| Material | Aquarium use | Recommendation | |. |. |. | | PETG | Submerged decorations, caves, holders, brackets | ⭐ Best overall | | ASA | Tank equipment, especially around UV/light | ⭐ Excellent, but harder to print | | PLA | Decorations/temporary parts | ⚠️ Usually okay short-term, not my first…
PETG handles constant water exposure well and is easy to scrub.
For anything the fish can rub against, round all edges and avoid tiny gaps where a fish could get trapped.
One important distinction: the base plastic may be suitable, but pigments/additives vary by filament manufacturer.
I would avoid mystery filament, metallic/glitter additives, antibacterial filament, glow-in-the-dark, and anything containing copper or other potentially leachable additives.
For prints such as caves, tunnels, plant anchors, filter guards, feeding rings, air-stone holders, or custom aquarium structures, I'd generally use 4 walls, 20–30% infill, and enough top/bottom layers to make a solid shell.
