What can be kept with Goldfish in a cold water tank? I'm not talking specifically in my 10 or 11 gallon tanks but in general. I know a few, can anyone add on?
Rosy Red Minnows
White Cloud Minnows
Dojo Loaches
Ghost Shrimp
Crayfish, African Clawed frog(Provided your fish are big enough to defend themselves), koi obviously, Weather loaches, Minnows, tadpoles/frogs(Provided the fish aren't too big)... the list goes on and on.
