Crayfish and betta

[Pckerfreak44]

I got a smallerish crayfish from my friends pond and I decided to put it in with my betta Ina 10 gal tank. Anything I should know or shouldn't do about them? Any advice would be appreciated.

A wild-caught crayfish? I would be concerned about disease or parasites. And do you know the species? It could possibly be able to harm your betta or your betta might attack him.

If your friends pond has been established for awhile and it's had a healthy population of crayfish then your chances of contaminating your aquarium are minimal. Most diseases invertebrates carry will only affect other inverts. There are exceptions though. As long as your crayfish is a good bit smaller than your betta he should be safe just monitor the situation for awhile

IMHO, someone will have a tasty lunch.is it a male betta? Keep your eye open for aggression.

His pond is really old. And my betta was really curious at first but now he seems to not care anymore.

Dude most likely the betta will die. The cray is most likely aggressive.

I'm gonna keep an eye on them. My betta usually never goes to the bottom of the tank.

And it's a male betta. And I've had him in a community tank before and he showed little aggression. I had to move him because he was getting picked on.
