Why do my fish keep dyin?

Question

i have a simple fish tank for cold water fish. it is clean often, and my fish are fed regular. but it seems my fish either die within hours of bein put in the tank or within a few weeks, they never reach full life, none of my fish show any signs of infection (white spot). any suggestions?

Answer 1

have you a working filter and pump in your tank,what size is your tank how many fish are in the tank.
are you over feeding them which can produce high nitrate and ammonia levels,are you doing water changes ,not a full water change 25 percent weekly,what fish do you have in the tank?
Ive a marine and tropical tank and i check my nitrate levels every day and my tropical tank has a 25 percent water change every 2 weeks and is fine i give my fish a pinch of food once a day and ive had one fish die in 6 months maybe your nitrate and ammonia levels are to high
when you change the water are you putting in like safe tap which makes the chlorine in the tap safe for fish,if you are are you adding to much,

1. Have you overfed the fish, they only need a little food.
2. Do you have a flourescent lamp with the tank, if so, check to make sure it is the correct type, some give out substantial heat which cold water fish hate.
3. Do you have a bowl or a tank, if it is a bowl, get rid and invest in a tank, the oxygen gets to the water through the surface and there is not much surface water in a bowl.
4. Depending on where you live there are a lot of chemicals in tap water, there are 2 ways of dealing with this, either get more chemicals from the pet shop to rid the water of the harmful ones, or the best idea is to leave the water that you want to put in your tank standing without fish, preferably with a pump running for a minimum of 24 hours. This helps the chemicals to evaporate.
5.If none of the above help, and your tank is definitely very clean, the only solution is to ask a very good pet shop or vet.

Sometimes, the colored pebbles people often place in the bottom of the fish tanks to give the tank a more colorful 'personality' for thefish can be poisonous to the fish. It seems that the dye used to color these pebbles is highly toxic to the fish and can kill them within 24 hours after being exposed to it.

It could be that the air filter is clogged with something, maybe dust and this is getting into the breathing system, polluting the water the fish are in. Check the filters to see if this might be the cause of the problem.

The other thing it might be is the type of tap water you are using in their tanks. When we had fish, we always kept a gallon jug of tap water under the sink, so that when it came time to change the fish tank out, we could use the water in the gallon jug and not the water directly from the tap. It seems that water from the tap contains low amounts of chlorine and this might be too strong for the fish when first exposed to it. But by allowing the tap water to sit in a container for a day or two before using it, tends to reduce the chances that it would have any ill effects upon the fish.

Whatever the problem, I wish you the best of luck in solving this problem.

Answer 4

Are you using tap water? The chemicals in there can kill fish. try cycling the tank with some plants and white clouds for a few weeks. Do a 20% water change every week or so. Make sure you have a good filter. Also make sure the surface area of a tank is big enough like gold fish bowls they are too small for fist to live happy. Good luck, feel free to email as you go on I have kept fish for years.

Answer 5

firstly, a good water ager removes chlorine and cloramine
secondly, some fresh aquatic plant
thirdly, put some charcoal in a piece of stocking in the bottom of the tank to aid filteration
make sure that the tank is not in the kitchen uncovered or in the bathroom fish do not like aersols
dont change the water except once a week and then only 1/3 and use the water ager.

Answer 6

There are many websites on Fish Aquarium if you search on Yahoo. When I stared my little aqarium, I had lot of trouble.
1. Ammonia goes up and it is poisonous for fish - get neutralizer for ammonia and test kit. If ammonia is high, change half water and add neutralizer. Do not feed too much.
Feed every other day. That will reduce ammonia.
2. Water has to be soften with softners and dechlorinated. Fish get streesed if there is chlorine in water.
3. Do not clean and change water often as it washes away beneficial bacteria which is needed to clean up ammonia on regular basis without using neutralizers.
4. Get Rosy Barbs, they are strong and easy to take care off.

Answer 7

Are you putting Safe Guard in the water after cleaning.Also you
should only clean the tank fully(whole water change)every 5-6
weeks.Change a third of the water using a suction tube pipe to
clean the bottom.Wash the filter and pads every 2 weeks When
you do the third water change.Always wash the pads in tank water and not under tap water.You wash away bacteria which
will disease or kill your fish.I suspect this is what you have been
doing.Wash ornaments if you have any under running tap water.But never filter pads.

Answer 8

you need a filter, ph kit, dechlorinator if you use tapwater, aquasafe for well water because it can have parasites that dont hurt you, but kill fish, always save 12 your water when you clean the tank. and get a water heater. a tank is a tank is a tank, always use these amenities. sounds like you have a "green tank", set it up with all that stuff and let it set empty 3 weeks, then put in 2 or 3 fish, and a algae eater, keep the water temp 70 to 75 degrees F.

Answer 9

hey!

feed them once a day with proper fish food

clean tank when it looks dirty
and you NEED to leave them for at least 2 hours in a container e.g large bowl (full with water obviously) out of the fish tank other wise the water is to cold

MOST IMPORTANT THING
they need a good working pump

if one of your fish ever gets a white spot dont panic goldfish get white spots its normal only start to worry if they have loads of white spots i have had my gold fish for 7 years and she has had white spots she's fine

good luck x

Answer 10

You need to remove the chlorine from the water every time you change some water from your tank. you can get this from all pet stores, it's water conditioner.
I used to use 'Stress coat' as well. if restores the slim coating that fish can lose when stressed.
Also make sure you have good filtration .. and DO NOT over feed.
