my goldfish are staying on the bottom of the tank what could be wrong?

Answer 1

Could be the loss of Balance therefore unable to rise from bottom of the tank.
Try adding aquarium salt (or non-iodized salt).
Also:
As a general rule of thumb, fish diseases are the result of improper husbandry issues eg not cleaning the tank often enough, introducing new fish without quarantine etc. Most fish diseases are better prevented and this can be done by ensuring good husbandry practices and that water quality is in tip top shape. The problem with fish disease is that because it is usually a consequence of poor husbandry, it is not often easy to establish that there is just one type of problem going on eg it's only a fungal infection, or purely a bacterial problem. A lot of the times it's a combination of the lot and one just seems to have affected the fish more than another. Whilst the best treatment for fish disease is to come to a proper diagnosis first BEFORE embarking on treatment, more often than not, the ALL in one type treatment regime to cover your bases is utilized for convenience sake.

The first sign of fish disease is usually lethargy and loss of appetite - your fish may just lie on the bottom of the tank a lot or seem 'sleepy' - further investigation is required to get down to the bottom of what the cause is. Your first action point when you notice these first signs of fish disease is to check your water parameters (water quality).

Answer 2

To better answer your questions we need to know
-what size tank?
-how many goldfish are in it?
-what do you do when you do tank maitenance?
-how do you do the tank maitenance?
-what are your water parameters (ammonia, nitrite, nitrate, ph)?

Do an IMMEDIATE partial water change. Do not take out more then 50 percent of the water. Make sure to vacume the gravel with a siphon to remove fish waste and excess food. Make sure the new water is dechlorinated and the same temp as the tank water so you dont shock the fish.

Answer 3

If the fish are at the bottom of the tank, you should check if there is air going into the tank (cleaners, decorations etc.)

Answer 4

fish usually hang around the bottom when they are stressed or scared. Check your aqaurium and see that everything is ok. Also if you have the wrong decor or arranged it wrong then you should fix that. Look up more on fancy goldfish to learn their habitat

it may be flutes. Flutes are bacteria living on your fish. It multiply quickly and cause you fish to stay at the bottom, not moving. This allow the bacteria to multiply even faster. There are some chemical to kill the flutes or you migth try salt bathing them. This can remove the flutes also.
