I bought a brand new tank for my two fantail goldfish.. they had been in it for a couple of weeks and were absolutely fine so I bought 2 smaller fantails to join them. After a couple of days I found one of the new fish kind of stuck to the filter and it died later on that day. The others still seemed perfectly fine. Two days later I found the second new fish stuck to the filter.. i turned the filter off and he swam away but went back later on an found him stuck to it again and he died.
I covered up the filter nozel as best I could to stop the fish going near it but two days later I have found one of my original fantails floating on the surface struggling for breath with his tail pulled apart (it was immaculate yesterday). The last fish is fine (touch wood) but I really don't know what's going on.. I didn't think the fish could get to the filter but still managed to be injured. I've had to uncover the filter nozel as the tank is not cleaning properly without it.

Healthy fish would be able to swim away from a filter so that is not the problem. The new fish you added could of have something wrong with them and since you didn't quarantine them, at least you didn't say you did, then you infected all the fish. The tank could also be too small and if it is not cycled adding more fish to it made the ammonia get even higher and that alone can kill them all. If you don't know what a cycle is then I suggest you look it up, all tanks need to be cycled in order to make the water safe for the fish. Also goldfish need a minimum of 10 gallons each when babies so make sure your tank is big enough for them.

Yes it sounds like ammonia killed your fish. The filter size doesnt matter, the fish werent strong enough to escape because they were sick.
You should do a 25% water change today, and then repeat in 1 week.
You dont mention the size of your fish tank, but 4 goldfish will create a lot of waste(goldfish are very dirty), and you really should have at least a 30 gallon tank for 4. Your filter should be rated between 30-60 gallons.

I've had the same problem. All of my little fantails died like that. But! I think I found a solution. Take a pair of pantyhose, and cut out a piece big enough to cover the intake. That way, it will still filter properly but the slits in the intake are covered. Only thing is, yes you'll have to clean the piece of hose every so often, once you notice the water's not coming out fast enough. I've done that, and it's been a great success with my three little fantails.

It sounds to me like your tank is still cycling and the fish are being poisoned by their own wastes.
Fish tanks go through a process called the nitrogen cycle where bacteria are established that break down their wastes from ammonia into nitrates. This process typically takes 4-6 weeks and until it is complete you cannot add more fish without taking a chance of having them all die.

if fantails are big then i advise you to get a new filter or a different kind of filter
if they're small fish then just get a goldfish bowl
and forget the filter
or you can get different fish and see what happens to them if it's the same problem then it's the filter that needs to be replaced

I look to keep in innovations a ingredient referred to as white fin in fish and it became led to by using a mite in the nutrition that they were given so that you ought to attempt a partial water replace and a replace of nutrition attempt PETS AT living house own Goldfish Flakes they have each thing that sparkling chilly water fish want are also you treating the water before you placed it in the tank with both tap secure or rigidity tyme and did you wash any gravel in organic tap water in case you probably did drain the tank and wash it in sterile water or boiling water in case you do not have sterile ,desire this helps.

I don't think the problem is the filter. Are you over feeding then. You should only be feeding them once daily and small amounts. I think that you have a nitrite problem due to over feeding. The fish will go to the area of moving water to gain extra oxygen. Get a test kit from your local aquatics and take his/her advice.

Well the tank might have been to crowded(how big was it?) and the ammonia levels might have shot up causing the fish to get sick and just to weak to swim away

.That happened to my fish and it could have been that the new filter was to strong and was pulling them closer to it and was cutting the gills, so they would not be able to breathe.
