Maybe it recognises you as the person who feeds it and is hoping you will give it a little treat to nibble on.
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.
Rule of thumb is to not mix tropical fish and goldfish.
Puffer fish are very aggressive fish and will tear the poor goldfish to pieces.
You don't. You look after the fish properly and nature will do the repairs just fine provided you follow the rules. The basic rules for keeping fish healthy are. :- 1 inch of fish needs a minimum of 1 gallon of water.(a goldfish is a 10 inch fish) :- Every fish tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water replaced every week. If you follow the above rules and keep the fishes water at around 65F to 70F it may survive. If you fail to follow them I can guarantee that your fish will not survive for long.
it depends on how big it is if it is a goldfish or beta it can be in a bowl.If it is one of those big tiger fish or aqarium fish then put it in a big tank. A fish will grow to the size of the tank or bowl. For instance, say a goldfish is in a tank, it will not grow as big as the tank; however it will grow big enough to be able to swim in their environment. The fish will not overgrow the tank. I had a six inch goldfish in a thirty gallon tank.
Goldfish do not get pregnant.
A properly working filter can really improve the living conditions for your goldfish and will almost double the tanks holding capacity. The tank you have though is not large enough for any kind of goldfish. 1" of fish needs 1 gallon of water. Your goldfish will grow to around 10" if given reasonable conditions. That is going to max out your tank with just 1 fish.
Yes they will, to prevent this you could buy a fish tank cage.
No, goldfish are freshwater fish. Any goldfish you buy in the store are tank bred and not wild caught.
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.
