Marmokrebs

[Sursion]

Someone near me is giving their Marmokreb away for free. I was thinking I could give it a good home. My main question is, how do they do in a community aquarium? I know crayfish are naturally aggressive, but this person told me that Marmokreb's are a very calm and peaceful species. But I want to get a second opinion first. I'm not going to bring in something that causes chaos.

Thank you for reading :)
