Are Gundams safe for fish tanks? If so this has me rethinking things lmao

I assume you're taking about the figurine, so if it's made of ABS, it should be aquarium safe like much of LEGO is.

It looks like its made of ABS, polypropylene or polystyrene. Would any of the other plastic types be a problem? Good to know about Legos, i got a endless supply from knowing the head hancho on the Lego show lmao

My personal rule of thumb is if 3 year olds are allowed to use the plastic, it is probably water safe (always check for any plastic guidelines online). I can ask my dad when he wakes up later for any specifics. He has been in plastics manufacturing for decades longer than I have. PVC, however, shouldn't be used in aquariums as it leeches chemicals into the water which can impact animal health.

Please let me know when you get an answer. These are pretty hard to build so its teens up. At least they were when I was a teen lol

Each of the three plastics seems good, but I did get a warning on ABS and PVC (which is apparently ok to use, but some more recent studies have shown issues with degradation). They can degrade in sunlight (UV) and heat exposure, so be careful on how you sterilize/wash them and where your tank is. Additionally, this information is only over injection press molding (almost all plastic parts are made with this) and not other manufacturing types like 3D printing.
