dying fish
« on: June 23, 2010, 04:01:57 PM »

Hello!
I have a 10 gallon tank with 1 small fantail goldfish and 1 snail. I thought I would buy just 1 more to keep my fish company. THe only problem is the new ones keep dying after about 2 weeks! I've tried 4 already (not at the same time) and they all died. I"ve changed 90% of the water each time one dies and I've got several test kits and the water is fine. The one fish I've had for a year and he's doing great, I don't understand why the others don't make it. They've all been really small, about an inch long including tail.
Any advice?
Thanks

Its probably from stress. You really should only have 1 goldfish per 10 gallons, otherwise you risk over crowding.

it could also be that your fish are all kind of sickly. Where do you buy your fish? How big is your filter? Why are you changing 90% of the water? that screws up the biological process. the most you should be doing is 10-15% water changes, especially in a 10 gallon.

Worst thing to do is to change almost all of the water. 90% FAR TOO MUCH. Your tank never cycles in this case.
Before you introduce another fish into a tank you should keep it in quarantine for about 3 weeks, in a hospital tank

and as Kat mentioned: 10 gallons per fish, otherwise your tank is overstocked

It could also be where you are getting your goldies.  Are there other sickly-looking ones in the tank?  Feeder fish tanks are bad about keeping healthy fish.  I know we all want to rescue those poor souls, but they're usually not in the best of shape.  And yeah, 90% is a bit too much.  Stick with about 15% and do keep it in a quarantine tank.  You can even put both tanks close by so they can get a good look at each other!

When you test your water what exactly are the ppm (parts per mililiter) on the test results?  Any ammmonia at all showing up will make a fish go into shock and sometimes even a small amount of nitrites can stress your fish out!  It's important to test your water BEFORE and AFTER adding any new fish for the first week or two.
I agree with the rest on how important it is to quarantine the new fish.  If he has any other diseases or parasites he is carrying then you risk your "older" fish from getting those.  Fish illnesses and parasites are so contagious! Smiley

Small fish 1 inch are very sensitive.  Even an abrupt, different water chemistry from the water at the pet shop to your tank water can make a fish go into shock.  I always place my fish in a quarantine tank and float the bag for at least 10 min., then add a cup of the tank water to the bag and let it sit in the tank for another 10 mins.  Then release the bag to the new tank.. I keep the lights off too for the first 24 hours.  Then start gradually leaving the lights on for longer periods of time when I feed.  I very sorry you are losing your fish.  It might just be the petshop got a bad batch of fish too. Undecided
I hope our posts help some.

When I came home I was devastated, so was my hubby. Went to some pet shops to have a look at some plants, compare prices, etc and also looked at the fish: one pet shop had 2 dead fish floating in 2 different tanks and in other tanks quite a few fish either VERY quiet or bottom sitting. It just broke our hearts, And then  -you wouldn't believe it- in the 2nd petshop there was a goldfish floating on its side, just gasping a bit and then a few "normal" swims and then again floating on its side. We called a staff member, he said it is to late they have to put him down. HOW SAD !!!  Cry  Cry

We know that we WILL NOT buy our fishies from those 2 shops, neither the plants... who knows what kind of desease is going on there... Cry

Lucky to come home and see how wiggly ours are, just that they don't wiggle their finns off... Cheesy

Nothing more repulsive than going into a petshop and seeing dying or dead fish in the tanks. Angry
They could have taken the "dying" fish in the back room and put him in a different hospital tank. Angry
People should be treated like a guest in their stores!  There are some relaly nice petshops and then there are some that don't seem to give a **** about their customers or their pets. Sad

CHeck the tanks the fish are kept in at the petstore. If the goldfish look happy then its probably safe!
