Goldfish can live for up to three hours out of water. It also depends on where your goldfish lands. If they landed somewhere moist or in the puddle of water they spilled out of their bowel, they can survive for around three hours. However, landing on a dry surface will kill them in about one hour, due to lack of breathable oxygen for their gills as well as ...

Fish swimming with their mouth constantly glued to water surface is a sign that they are gasping for breath. However, the reason for them being short for breath usually isn't the low oxygen concentration in the water itself, but toxic effect of water pollutants: ammonia (NH3), which burns fish's gills and disables them from extracting oxygen from the water; ...

Too long for a comment, so an answer that might help future readers. How old are the fish? What sex? Sometimes pushing about is male fish trying to squeeze eggs out of female fish. In my experience, female goldfish get eggs round about 3 years of age. Males get breeding tubercles about 1 year. Sometimes biting and pushing just fish defending territory, ...

The only way to improve a fish color for real is with good food with beta carotene, I remember tetra brand having some of them. You can check deeper information about that here: http://www.seacolors.eu/images/NPR_61_46-49.pdf Is not going to be magic and will take some time. You can also use home made food but that's a more complex task as well as more ...

The snakes stop eating fish when there are no more fish. You can try killing the snakes, but they are fast. I did kill one by putting a fish trap under the water; the snake went in, could not find the opening and drowned. If the snake is slow and mostly black, it is probably a cottonmouth, which does not eat many fish, but you shouldn't mess with it.

THIS IS A MEDICAL EMERGENCY! Your fish may be infected with the viral infection called lymphocystis. There is really no direct cure for it, but your veterinarian can suppress the virus until it eventually stops. Many prayers to your fish. This is a decision you will have to make yourself. As well with that, it will not go away on its own. I would not ...

I would say just stopping to feed anything else other than bloodworm should work after some time - hunger is the best spice; if there isn't any other food, then ultimately your fish will naturally get convinced to eat what is available. Fish need surprisingly little food to survive, but will happily eat any available excess that they could physically consume ...

Goldfish are very hungry creatures. They will happily eat your low grade red cherry shrimp. When I was younger, and had no experience of keeping goldfish, my family put 10 beautiful Amano shrimp into a goldfish tank not knowing that goldfish would chow down on shrimp. The next day most of them were eaten. Shrimp are edible for goldfish, as evidenced by the ...

I know you fish is an indoor fish, but all fish have similar needs. Our outdoor Koi have many of the same needs. I agree with Omar and Lila. Our pond was built incorrectly and we had to get extra and better equipment to filter the water and add new water from waterfalls as the fish grew from 9" to 20". Test the water weekly and assure that your ...

First thing you should do is isolate your fish on a medic tank just in case it does have an infectious disease it could transmit, but also for you to be able to give them some treatment without affecting the rest of the population in your tank. Secondly, observe very well. Take pictures and look for anything different than usual. White dots like sugar, ...

Bro... You didn't change the water for a YEAR? Plus the tank is too small. What happens is the poop they produce creates levels of different stuff in the water, like ammonia and nitrogen, and too much of the latter will cause permanent brain damage. The other also has negative effects and this can stunt growth. Having a small tank also stunts growth. Your ...

Setup a fan pointing across the tank as a form of evaporative cooling. I assume though that would cool the top layer of water more than the bottom and I wasn't sure if the differential in temperature may make things even worse? A fan is a fantastic method for lowering a tank temperature efficiently; when researching methods to effectively cool a 60 gallon ...

First of all you will have to be sure you have good filtration, your pump and filter needs to filter all the water at least once every hour. The UV bulb needs to be changed every 6 months of use as the UV light output will degrade over time. The glass of your UV lamp needs to be cleaned when you can see it is dirty; you can use vinegar if there is limescale ...

Too long for a comment but not really a proper answer, so some advice. I’ve heard of "ammonia spikes" which seems to tally with your story. I’ve had them myself: beautiful fantail, white tail, red lines appeared one morning but all readings were in the safe limits. No other fish affected. The blood streaks didn’t really disappear, either, although ...

You are probably over-feeding, putting too much nutrients in the pond. I have a few ponds, never an algae problem, sometimes algae in the first month as they mature. I think algaecide is just the wrong thing, it kills regular plants in my experience. Feed less and when algaecide is gone, put in plants, they will out-compete the algae for nutrients. Duckweed ...

I do not think the swimming problem is related to the increased bone density so you need to take a look at other possible causes, it sounds to me like this might have a neurological cause like nerve damage. Swimming normally for several hours before the symptoms begin is a bit strange, had it been swimbladder problems it should have been a constant problem. ...

It seems that your NO3- levels were too high, so the fish jumped out of the tank and you water quality was so poor that even a full water change didn't do the job. It was probably the lack of plants and good filtration that was hurting your fish more than the fall itself.

Update: The wound is almost gone and healing well. What size tank is recommended for 1 fancy goldfish and a large sucker fish and a baby sucker fish. Should it be heated or not. When should i do water changes?

Keeping koi and goldfish in the same pond is not a problem at all; both types of fish are in the same family with the same needs, same food, water and temperature. Koi and goldfish will compete over food in the same way as all other fish living together will do, so this is not a problem at all. To be sure all your fish gets the food they need, you can spread ...
