probably a 20 gallon aquarium
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.
No, goldfish will not grow to the size of their tank. They will continue to grow and may become stunted or unhealthy if kept in a tank that is too small for their size.
The size of a tank can affect the growth of goldfish. A larger tank provides more space for the goldfish to swim and grow, allowing them to reach their full potential size. In a smaller tank, goldfish may be stunted in growth due to limited space and water quality issues.
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.
No you schould not have that many fish in a one gallon tank. Thats the size of a big betta bowl. And because they are goldfish it is worse their poops are toxins
The size of a goldfish tank can affect the growth of the goldfish. A larger tank provides more space for the goldfish to swim and grow, leading to healthier and potentially larger fish. In contrast, a smaller tank can restrict the fish's movement and growth, potentially stunting their development.
A 5-gallon tank is not recommended for keeping a goldfish. Goldfish require a larger tank size to thrive, ideally 20 gallons or more for a single goldfish. A larger tank provides more space for the goldfish to swim and grow, as well as better water quality.
Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger. But goldfish won't grow at all in seawater; they aren't saltwater fish.
Yes, as long as your tank is big enough for 3 goldfish. It should be at least 35 to 40 gallons in size even when your goldfish are babies.
You should not have goldfish and platies in the same tank ever.
Fantail goldfish are a hardy breed, strong swimmers and they compete well for food with the ryukin, shubunkin, comet or common goldfish; making these goldfish breeds good tank mates for your fantail goldfish.
No it will not. It will be runted by the lack of room. In order for goldfish to grow to full size they should be housed in ponds or very large aquaria.
