Yes. I have a five gallon tank with two goldfish and a blue crayfish and they have lived happily for several months. Granted, the crayfish may snap at the goldfish, but if you choose fast goldfish they should be fine.
A goldfish can live in an opaque glass tank as long as you keep up with necessary water changes. Like a small outside garden pond goldfish are only viewed from the top.
an aquarium or a fish tank

Rule of thumb is to not mix tropical fish and goldfish.
No; goldfish have bilateral symmetry.
No. A 10 gallon tank is barely big enough to keep a single goldfish in.
Yes, there are several species of freshwater crayfish available in the pet trade. A single crayfish can be kept in a 10-15 gallon or larger tank.
no they need at least five gallons each. a thirty gallon tank is a good size tank to keep goldfish in.
i have a turtle by himself and i want to put it with the crayfish because the crayfish is eating my goldfish is that a good idea
Crayfish of the same sex are incredibly prone to fighting since they are very territorial animals. If you have a large tank with plenty of hiding places, it is possible that the two can coexist peacefully.
Most people would keep goldfish in a bowl or tank, filled with water. You can always add scenery such as pebbles plants and castles :D
Very large peaceful fish. i would sugguest tinfoil barbs.
