They are fantastic. Some years ago I got a sudden urge (from seeing them on subreddits) to grow these in my aquaria, but then I looked at several aquarist forums and realized that I shouldn’t. Really shouldn’t. They kind of don’t seem like they need more habitats to thrive in.

Are they invasive or something?

[–] Seleni@lemmy.world 32 points 2 days ago

More like incredibly aggressive. They are a type of algae after all. If you don’t keep a firm leash on them they’ll reproduce enough to drain all the oxygen and nutrients from an enclosed system like an aquarium.

Plant tribbles, if you will.

To give an exceptionally brief explanation:

  • Yes.

Not that exceptional.

I suspect that they reproduce quickly, since it is a species of algae. I don't know much about this topic though.
