Guppy Problems

[CT 240 GUY]

I have lost two guppies in the last two days. One Male One Female. I examined them there were no marks or injuries. Does anyone have any idea what this could be.

I am starting to get a little frusrated with Guppies it seems they are a 50/50 Gamble.

Any suggestions would be great.

Setup? Tankmates? Source of fish? Recent acquisitions?

I think i got my problem working out. After many test I found out that my Nitrate was at a toxic level. I did a 75% Change and I already see inprovements to the tank. I am one of those cant wait to get fish in kinda guy and I payed for my lack of pateince. I also balanced out my PH which was high. I have 4 Mollys Two Guppies 6 Neons and 2 Swordtails. I am going to watch my tank very carfully and see what happens from here. I cant say I am sad because of this problem I now have a much better knowlege of Aquariums.

Just in case...what are your test levels?

[Lobo.]

How big is the tank?

[CT 240 GUY]

The tank is a 20G
I PH was 7.8 Range
Nitrate was 3.2 Range
Harness was 120
No Amonia (sp?)

After I did a water change and let it run Nitrate was a lot lower in the 0.5 Range.

After I did the water Change The fish seemed to be more active. I notice some of my fish are stressed.. I hope the can ride it out.

my plants are Flourishing Very Green and healthy.

I also realize i have too many fish and can be causing my Water Levels to flucuate.. But I think I will be ok...

Guys I cant thank you enough for all your help. YOU HAVE MADE MY AQUARIUM A BETTER PLACE :)

Ammonia should be at 0
NitrIte should be at 0
NitrAte should be 0-20

Nitrates is the by product of the cycle. It tell you that the bacteria is working.

So after doing my 75% water change, thinking my fish would be ok. This morning I go check out my Tank my female swordtail is dead... I have no idea what it could be. I was thinking maybe stress from the water change??
Can a fish die easily from a temp change over night?...I am thinking maybe my temp changes to often at night due to my AC... But i always make sure it is steady
Any Help Would be great at thiis point..
Thanks guys/girls.

If you don't have a heater and the temp. in the tank varys more than a couple of degrees, you need a heater. It might not have caused the death, but temp. fluctuations are very stressful for the fish. Your ph is fine at what it is, changing it with chemicals is almost always a bad idea, they do not last long term, it changes again everytime you do a water change, and a fluctuating sudden change in ph is also very stressful for fish. I would guess that may have been the cause of your most recent fish death. Water changes are good for the fish, even a large one, as long as the temp. is the same and the ph is very close.

Well I will set my Temp to 80 Degrees When my AC is on my room and the water both get cooler.

[Kasakato]

Sounds like temp movements to me. Whats the high and low of the room?

[CT 240 GUY]

I would say overnight it gets to 78-82

Really not that bad

I also balanced out my PH which was high.

This is my next guess at the problem... What is the ph normally and what are you doing to "balance it out"? If you are adding something to alter the ph, then do a water change and it changes drastically, going right back to what it is out of the tap, this can cause problems.
