Small cancer, red

[Autumnsky]

Here was my little guy lower left above the white thing and marble.

My female had maybe 30 babies and they ate each other, little cannibals. All left was one, this was in a 6.6G Fluval Edge tank. They never seemed to bother the nano fish.

I am checking why the photo doesn't appear here.

Thanks for the hint. I'll try to get the same great.
Or, if they are small separately in a basin.
Greetings.
