Crayfish questions

[Brox]

For a 40 gallon,
3 Guppies male:female ratio
12 neon tetras
6 zebra danios
3-5 loaches
4 mystery snails
2-3 Otos
Shrimp
Can I add a EB or a white crayfish

I have a 55 gallon tank. 5 danios, 5 tiger barbs, 4 neon tetras. I purchased a crayfish about a month ago and SO FAR no problems with him eating my other fish. You will find a lot of different opinions here regarding crays in community tanks. Mine just molted the other day and he is now much bigger. I wouldn't be surprised if he did get one of my fish one day but for now everything is ok

It will not work long term. Your shrimp and snails would be the first to start disappearing at night.
