Some snails and seed shrimps hitchhiked in. Fine with me. They can take care of detritus and dead leaves. It's not like I'm feeding anything in the tank so they shouldn't get out of control.
I don't know what happened with this pygmy chain sword. The one sent out runners. And then it stopped. This is pretty much as far as it went. And none of the other pygmy chain swords sent out runners at all. They've been there since the end of June.
You're still in the nothing nothing nothing phase. Wait for it...In my experience, they do nothing and nothing and nothing and TAKE OVER THE WORLD!
