it depends on the size of the fish and the tank. if the fish are to small the may fall prey to the crayfish, this problem can be avoided if you have a large tank but, most people would advise that you don't mix these two types of animals
I agree I caught one without claws and it is doing fine in my tropical tank but it is still small.
A crayfish isn't a good idea if you have small fish in the tank.
Crayfish are invertebrates, freshwater lobsters, not fish as a previous answer mentioned. As for placing them in an aquarium, you first need to research what size the particular Cray species you want to keep gets to, that can be anything from 3"-4" to over 12"-15" not including claws! The majority of Crays are also opportunists, so may well eat any fish that are in the tank. They are also escape artists so need a secure lid. Most Crays are territorial, so it's usually best to keep one in a tank alone, no tank mates at all.
If you want to keep Crays, find out the species (latin name) of the type you're interested in and research from there!
Yes, you can catch crayfish in Missouri, but you need a fishing permit to collect them for personal use. Additionally, keeping crayfish as pets may require a proper setup, including a secure tank with appropriate water conditions and hiding spots for the crayfish. Make sure to follow local regulations regarding keeping crayfish as pets.
yes ghost ants make really good pets
Salamanders make great pets.
red eared slider turtles make good pets.
Climb out of Tank -- I have a red claw crayfish ( cherax destructor ) and it climbs a lot, also likes to make holes and attack my fish. Do not keep slow moving or long fined fish in the same tank, as the crayfish will attack it and soon eat it.
Thorny devils can be good pets. It really depends on who you are.
