Hey all,

I want to permanently house 2-3 black mollies in my 15g observation nano tank. All the fish I quarantine go through a 2w period in there after they finish copper + prazi in a separate quarantine tank, and before I put them in my DT.

The trouble is that I often get very small inverts/fish in there (e.g. urchin clingfish), and I was wondering if you've ever noticed your mollies being aggressive to any smaller inhabitants like that? Especially if I get a breeding trio. Thanks in advance!

Mollies are not aggressive or territorial, there will be no issue and if there will be i am going to be truly surpriced, just make sure you dont put something so small that it can fit in their mouth because they eat anything that fits inside their mouth

Thanks for your reply! I do have some inverts that are barely one inch in there, maybe a bit less, but I can't imagine them fitting into their mouths.

Yeah that Will be no problem, need to be much smaller, you will probably see the mollies pick at their shells if they have Shells for algae
