Yes

I don't know what catagory these fish belong in but I was wondering how hard are they to keep in a 30 gallon tank? At $10 a pop at Petsmart I was thinking of getting two of them and put them in with the 1 comet and 2 common goldfish I have in the tank and two crawdads. I was also thinking about buying a Jack Dempsy or a Fire Tiger Oscar. What is the best choice for a 30 gallon?

I once mad the mistake of keeping loaches and crayfish in the same tank. They get terrorized, and sometimes eaten, at night.
