What is a mind like a goldfish?
If someone says you have a mind like a goldfish, they are saying you have no mind at all.
No, all Goldfish are freshwater. NO! THEY ARE NOT BRACKISH LIKE MOLLieS! who like fresh water with a tiny bit of salt in it. goldfish do not need heaters but filters because they tend to be messy. goldfish like the water temp to be 20-23 degrees C but it's ok if it's a bit under or over. goldfish are not tropical like guppies, mollies, tetras, barbs, angelfish, etc.
There is no official shape name for a goldfish and there many different types of goldfish. The common goldfish has a shape like an elongated football (American football). Some fancy breads like a veiltail have a body shape much like an egg. Some goldfish might have short pointed tails or long flowing ones; they can have globe looking eyes, puffy faces or even have cheeks that look like blown up bubbles.
Shubunkin is just a fancy name given to a specifically coloured Goldfish. Breeding one with a Golden coloured goldfish will result in about 33% that look like a Shubunkin and 33% that look like a Golden coloured goldfish and 33% that look like a mixture of the two. The above results would only be accurate if the breeder fish are properly line bred and their lineage is guaranteed. Otherwise you could get anything from coloured…
Goldfish are a form of carp. They don't eat other goldfish, but they eat small flies. Sometimes goldfish like to eat tiny tropical critters such as ghost shrimp, but they don't eat other goldfish unless there's a huge size difference or if the other goldfish are frys. Occasionally, goldfish may nip on another goldfish's fins if it is weak. There aren't any specific goldfish that goldfish themselves target.
