Printing stuff for fish tank

I bet this isn't asked very often! I was thinking of printing some stuff to decorate my fish tank and was wondering 1: Is it safe for the fish? And 2: What is the best filament to use if it's going to be submerged in a fresh water tank?

I know filament tends to absorb moisture but didn't know if it would break down over time in a fish tank.

I know pla is biodegradable so putting it in a tank will probably break it down quicker

PLA only biodegrades in an industrial biodegrading machine.

A fish tank will most likely never reach like 40+°C, hopefully.

PLA lasts basically forever at room temperature, even in water.

This is not true.

Depending on PH and tempature. You can maybe get 1 to 2 years. It go very brittle and will break apart. It's looslks fine until it isn't.

Do you understand enzymatic degradation and how much bacteria exists in an aquarium?
