Answer 1

Simply
New tank, too many fish, too little knowledge. Find out more about how to set up a new aquarium and you will do better.
Care sheets and how to set up a new tank are available on my web site.

Answer 2

Ok, first off one week isn't long enough to cycle a tank properly, especially when you just dump that many fish in at once! How big a tank is it? What kind of fish are they? Do you have a filter on the tank?

If you have a 20 gal, then that many fish may be ok if they're guppies, but if they're something like goldfish, then yeah, you can expect them to drop dead from ammonia poisoning, especially in an uncycled tank.

Do NOT add ice to the water, sudden changes in temperature can shock and kill your fish! If they're tropical fish, like guppies, then you don't even have to lower the temperature unless its over 80 degrees.

What you can try to do is get some water that's close in temperature (or slightly cooler if the temp. needs to be brought down) that's treated with water conditioner, remove some of the old water, and pour the new stuff in. Make sure to remove the dead fish immediately.

It may not necessarily be the tank that's killing them either, if you just bought the fish, they may have died due to the stress of being toted around and dumped into a new habitat. Sometimes it takes a few days for it to catch up to them.

Please post more information, like what kind of fish they are, how big a tank you have, and what the water temperature is.

Answer 3

Twenty five fish is a lot for a new tank. They all produce wastes (ammonia, which is toxic to fish) but you don't have any bacteria in the tank yet that will convert the ammonia to nitrite (also toxic), then to nitrate (nontoxic in moderate amounts).

What type of fish do you have? If they're tropical, they should have water that's 76-80o. Do you have a thermometer to measure the water temperature? Is there a heater in the tank that might not be working properly? Check on that (unplug the heater if necessary so the water cools down).

You can do a 25% partial water change to help both possible problems - siphon the water out and add just slightly cooler water to the tank SLOWLY! (remember to add dechlorinator to the water) Too much temperature difference or adding it too quickly can shock your already stressed fish.

Is there a filter in their tank or an airstone with air pump? Warm water doesn't hold as much oxygen as cool water, so even scooping the water and pouring it back into the tank to create more movement can help your fish.

Answer 4

Um well there may be too many fish in there. Or the type of fish you have may not mix well together. How many species are in the tank? Or are these fish just dying and not being killed by other fish?

Anyway, make sure the type of fish you have in there should be in freshwater. If you don't have a filter and air tank thingy in there then you will need one soon. Also get a thermostat in there and make sure the water stays at the temp it is supposed to.

Answer 5

OK first u should set up the tank for a least 2 week before u put fish in it and u need 2 put aqua safe (it a water conditioner) in water and average temperature for tropical fish is72-82 and add aquarium salt and you should be good 2 go

Answer 6

Well sometimes it depends if you get salt water fish or fresh water fish. Also when you buy them at first and they are in the plastic bag, let them sit in the tank in the plastic bag for a bit floating in water so they can get used to the tempurature of the water in the tank. Did you put any chemicals or anything there?

Answer 7

i would start doing 25% water changes every other day -- like asap. more than likely your water chemistry is way off. do you have a thermometer to measure how hot it is? you might want to pick on up -- they are just a couple dollars. no more ice cubes -- ok? what kind of fish are they and how big is your tank?

Answer 8

did you add anything that was in contact with any chemicals or anythign that came from SALT WATER????? like ocean plants?

Answer 9

IS YOUR FRIENDS HAND DIRTY MAYBE THE CUBE GOT SOME GERMS DONT YA THINK....

Answer 10

Huh?
