10 Gallon Disaster
My son's 10 gallon tank is driving him crazy. He has 2 pairs of fancy guppies. He had 2 pairs of swords. Both females have died. We have moved the male swords into my 30 gallon tank. The male swords are doing fine in the 30 gallon tank now. I tested the water in the 10 gallon tank with the following results: Nitrite 40, Nitrate 0, Hardness 150, Chlorine 0, Alkalinity 40, Ph 6.2
The guppies are doing just fine. HMMMMMMMMMMM.......
Whats up Doc? :?

Nitrites are very toxic...they need to be 40ppm they're poisoning the fish...

Are you sure you have your nitrites and nitrates measured correctly?

Nitrite Level
I used Jungle test strip that checks all 6 levels at once. What will bring the nitrite down?

Well guys it's late here, almost midnight, and I messed up on my post. The Nitrate level is 40 and the Nitrite level is 0.

...well, to keep a long story short...the only way to deal with nitrates is through regular water changes... 40 ppm you're on the 'edge' of stressing the fish... could be what did them in...or not...hard to say at that level...

...but do more frequent water changes and keep tabs on the nitrates...if you can keep them to 10-20 ppm, you should be fine...

u said 2 pairs of each fish? sounds to me like the females were harrassed to death. the ratio for livebearers is 3 females to 1 male. so for 2 males u need 5 or 6 females so that they arent singled out and constantly chased.

Nitrate Levels
The Nitrate level is between 40-80. Will that cause the lips of one male guppy appear as being burnt? The other male guppy is fine.That is the best way to discribe it. His gills appear to be open and not moving. We did a 50% water change 3 days ago.

...nitrates are still too high...but I don't know if they'll cause 'burn'...I know ammonia will...

Keep doing water changes...even do 25% every day...until the nitrates are doing to 20 ppm or less...a little flucuation doesn't matter...but they shouldn't be holding steady at 40 ppm or more...

And it could be, as lioness said...that the males are harassing the females...the recommended ratio for livebearers is 1 male to 3 females (give or take)...

...if you're not interested in can have a male or female only tank...

Thanks Rue. We'll keep changing the water. Persistence will prevail.

No. That's generally where my community tank runs and my fish don't have any problems. Cardinal tetras tend to be sensitive and they are doing fine in the tank.
