Do goldfish need filters?
no..they can live in fish bowls without filters...just change the water every couple weeks
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.
It is best that all fish have a filter besides Betta fish. Betta fish don't need filters cause the filter pushes them over with their big fins. Goldfish should have a filter on there tank because they are often overfed. If you have a filter you won't have to change the water as often. The only fish that shouldn't have a filer in captivity are Betta fish.
You would need to add an agent (what is swallowing the goldfish). The passive voice is unique in English in that the agent does not need to be named. The goldfish was swallowed. The goldfish was swallowed by the... The ... swallowed the goldfish. It's generally acknowledged in writing that an active sentence, like the third example, is stronger than a passive phrasing.
While it isn't required that goldfish have an air pump in their tank. It can help your tank life by providing valuable oxygen to the fish. This isn't specific to just goldfish, as all aquatic life can benefit from the presence of a air pump. If you notice your fish swimming with their lips on top of the water level most likely they are trying to get air. This is especially true for tanks that…
It is NOT very right to keep a goldfish in a bowl. Not only do they become bored and unhappy, but it can cause health problems and stunt the fish's growth. However, the VERY least you can do for a fish in a bowl is the biggest bowl you can find. Also, goldfish NEED some sort of filter to live a reasonable amount of years, and filters cannot be put in bowls. I recommend at…
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.
Any other kind of goldfish can go, however, be cautious about the amount in the tank. Goldfish are hearty, but notoriously sloppy. The only other kind of fish that would really go with a Goldfish, and actually survive, would be a pleco or a hearty catfish. They eat all the junk left over by Goldfishes and can actually help maintain the tank (water clarity, gravel, longer lasting filters).
You need a lot of things, unless you are raising goldfish in a bowl. You need: (for a tank) A filter A tank (not recommended under 5 gal.) Goldfish food Gravel Live or fake plants (underwater plants) Air pump (not required) Choice of decorations These can be very expensive sometimes, but it will keep your goldfish living longer and happier than in a bowl
Yes, but your tank size needs to support it. If you mean that a regular goldfish is a long single-tail goldfish, then you need at least a 40 gallon tank just for the 2 fish due to the size potential of the common goldfish. If you mean a regular goldfish as in a round bodied fantail, or perhaps a ryukin, then you need at least a 30 gallon tank for the 2 fish.
