I'm not sure what you are saying by streamlined but if you mean the dotted line along the side then it is(*drum roll*) actually the nervous system. It detects ripples and stuff like that:)
The only issue I've heard about concerning housing goldfish together is any big difference in body shape or size. Bigger goldfish might be more aggressive towards smaller goldfish. Also, the more streamlined breeds (koi, comet, etc.) might have an easier time snatching up food, leaving little behind for the pudgier, slower fish (fantail, ryukin, etc.).
Probably, but usually the comet goldfish will get all the food and/or the other goldfish will become miserable. This has happened to me before and I do not recommend putting them in the same tanks. Try putting the fancy and comet godlfish seperate!
The "Comet" is a variety of Goldfish that has a long, single tail.
a goldfish,sparkling
no. i have had two big comet goldfish with my, little 2 inch fish, and they never ate him.
They eat goldfish food, the best place to get it is petsmart.they only eat goldfish food!( its unhealthy for a fish to eat other foods for there diet!)hope it helps!
Comet goldfish are the average pet, although you can now get funnier types such as (my favourite) Celestial goldfish.
Because a comet is a single tailed goldfish, and can grow very long, it will need at least 30 gallons on it's own
Sarasa are usually white with bright red markings
Almost all goldfish can get along! i would recommend a ryukin, black moor, ranchu, fan tail if your looking for a goldfish, but for other lil critters, maybe a freshwater snail, or minnows (you can find those at a local creek) or a freshwater frog, Just make sure you have a lid and a place for the frog to take a break and hop out of the water. Comet goldfish are very fast and somewhat aggressive. Fancy goldfish should not be housed with comets because fancy goldfish's unique features/bodies often prevent them from being able to compete for food. A good tank mate other than another comet would be a shubunkin or a wakin because these fish are built similarly to the comet and can compete for food. As for a community- goldfish really should only be housed with other goldfish.
Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.
