When goldfish swim up to the glass of the tank, does it mean they are smart enough to recognize people?
Goldfish sure are smart not in the sense as dogs are, but they are smart. They will swim up to meet you probably because they think you are going to feed them. They might not be able to differentiate between one person and the other but they do know that the people they live with are the caregivers. Know that they depend on you and hence love you.
Why is a new goldfish not moving in its bowl, when he is very much alive?
Well first of all, he probably hates being in a bowl. Goldfish do not like bowls even though humans think the bowls are cute. Put him in a tank with a compatible companion goldfish. Meanwhile watch the fish. Is he coming up to the top of the tank when you feed him? If he is then, heís probably just getting used to the new bowl. If it looks like he has difficulty swimming and that he keeps sinking to the bottom he might have a swim bladder disorder caused by too much dry food and bad water.
Why is a goldfish swimming to the top every once in a while?
Goldfish keep swimming to the surface of the tank because thatís where they get their oxygen. Always make sure that there is enough empty space at the top. Do not fill up the tank to the brim, as leaving space will give them the required oxygen. If your fish are normally active, swimming and chasing each other a round, donít worry if they swim to the top every once in a while.
Why do goldfish always seem starving?
Thatís because they are greedy! Donít get tempted enough to feed them whenever they ask for it because overfeeding will cause them more harm. Besides, goldfish can never starve to death; they are always nibbling away at something or the other.
Why would one goldfish lie motionless most of the time whilst the rest swim around? Is it a social outcast?
If you have different varieties of goldfish, make sure they are compatible. The slower fancy varieties might get stressed out by the faster ones like comets. Yes, they might feel like outcasts and keep to themselves. Some goldfish might even get aggressive with another and in that case you need to one that is being badgered to another tank.
Why are all the goldfish so lifeless and tend to stay at the bottom of the tank most of the time, like they are very tired?
If they arenít swimming as they usually do, something is definitely bothering them.
If you tank is brand new and the goldfish are having a problem because the tank has not been cycled. Wait a while and watch. Make sure you cycle the tank before you put them in because a new tank cannot deal with the ammonia that the goldfish produce.
If you tank is an old one and the goldfish are suddenly more still than usual it could be that the toxicity of the water is bothering them. So change the water. When your goldfish seem inactive, you must check the water for nitrites and the pH level.
