guppy changing colors?

Hi, I have 2 fancy tail male guppies, and one of them seems to change colors. One minute his body will be like a dark blackish color, and then a couple hours later I will look @ him and his face to his middle region is white, and from the middle of his stomach to tail looks black. So half his body is black and the other is white. Then at other times his body will all look one color? Is this normal?

From what I have gathered in my times of keeping guppies, their coloring will whiten when stressed...due to water parameters changing to include higher nitrite and ammonia levels, also when temps drop. Also when the fish is general stressed, like switching tanks or if another fish is stressing them by harrassing them.

Could it be the light hitting his body differently in the tank making him appear to change colors? If not, do a water test to make sure water parameters are safe, and go from there.

Hope this helps.

yea its just weird cuz his face looks like a whiter color up to his middle section, than the middle to the tail end of him is much darker like a blackish color, its like 2 colors at times and its so noticeable, like half white half black... i dont think its the lighting.. ive had the tank for a little over a month and i my ammonia is always .5 no matter how many 50% water changes i do.. one time there was hardly any in it, but its always .5.. i know .5 isnt horrible, since guppies and white cloud minnows which i also have are hardy fish, but i still shouldnt have any.... i have no nitrites and ph is good.. i think it was 7.4

Have you gotten any nitrates yet? Sounds like your tank isnt fully cycled, which can cause the color changes through water parameter stress.

Try smaller water changes every few days...say 15-20%...if the larger water changes arent helping and the levels remain low.

I checked my ammonia today and it was 0.. i didnt check for nitrates but i had no nitrites last time i checked.. when a tank is fully cycled, all the readings will be 0 right? its only a 2.5 gallon tank, so thats why when I do water changes, I do 50%.. I'm gunna only do 50% once a week now because the ammonia is 0 so I don't think it needs that many changes

How many total fish do you have in the 2.5 gallon tank? (Two fancy guppies would be the max amount of fish I would keep in that size, as anything else would cause serious over load and overcrowd.)

Is there a filter on the tank? (A lot of people dont use filters on tanks this small, but guppies need filters.)

Did I read right, that there is a white cloud with the guppies? If so, white clouds like cooler water, so if the water is too warm, the white cloud is at risk. If the water is not heated, the guppies are at risk, as they need at least 76F. So I ask, is there a heater on the tank?

A tank fully cycles when ammonia and nitrite are reading at zero and your nitrates are somewhere close to 10-20ppm. A 2.5 gal should cycle fast...my 5 gal cycled in like a week, of course it has a 10 gal filter on it, live plants, and I used a bacteria booster.

i have 4 fish and 2 ghost shrimp.. i wont be putting anything else more in it.. i have a video on the video section of my fish.. they all look very happy and seem to love the amount of space they have.. i dont have a filter on the tank but when i do water changes i dont use freezing cold water.. i use luke warm. the temp. of the water is prob around 72.... i have 2 white cloud minnows and 2 fancy tail guppies.. they are all very tiny fish but are doing very well.. ive had them for a little over a month already.. yes i have a filter in my tank..

Your tank is overstocked, or it will be when your fish grow up, if they aren't yet full grown. Your guppies alone need 3 to 5 gallons of water, depending on size and gender, and your minnows probably also need at least 3 gallons. I don't know about ghost shrimp, but for the fish alone you need a 10 gallon tank. Guppies get 2 - 3 inches, not counting their tails, with the females bigger. Also, if you have both male and female, you will end up with babies - lots of them, frequently. One of my guppies had 51 babies the other day.

Also, you need a heater. Water temp is usually 2 to 4 degrees lower than room temp, so unless you keep your house around 80, your water will be too cold for your guppies. They are tropical fish, and they need water in the mid to upper 70s.

Your ammonia needs to be at zero, period. Ammonia at .5 is too high, no matter how hardy your fish are, and guppies aren't that hardy these days. They've been hybridized too much to be as hardy as they are in the wild.

By the way, it's hard to cycle a small tank and keep the water parameters even over time. You'd be better off to get at least a 10g tank and cycle it BEFORE you put your fish in. In the meantime, do large water changes regularly, like 50% twice a week. One way to be sure you are doing water changes frequently enough is to get an ammonia test kit (liquid tests are better than dip-strip), and test for ammonia every day. As soon as it reads above zero, change your water.

As for your guppy changing colors - I have heard of a type of guppy that does change colors, called "spectrum" guppies. However, yours sounds like a half-black tux. I'd say you need to correct your tank issues - heat, water quality, and amount of water/space available, and worry about the apparent color changes later.

With the 2 fancy guppies...they actually only get to 1.5 inches. Two inches for a guppy makes it one of the larger specialty breeds, like the deltas.

White clouds, again, are cold water, so the way you are handling your tank now is fine for them...but not the guppies. Guppies MUST have a heater, hun. They need at least 76F temps. Colder temps is asking for issues, including but not limited to ich, funguses, bacterias...and the colder water stresses them out, causes their colors to fade, and weakens their immune system making them twice as vulnerable to those diseases.

To each his own on water change percentages, however, many will agree that smaller more frequent water changes are more beneficial over time. Even in a small tank, 20% once a week, or at times when nitrites and ammonia show up, is effective.

I have never had an issue cycling a small tank and keeping it consistant with water parameters. My 5 gallon, once cycled, has been perfect without issues in fluctuation. I think just the opposite, the larger the tank, the harder it is to keep it under control. Just goes to show how much fish keeping really is a matter of opinion (outside of the science/chemistry that goes into water parameters).

By the way, those ghost shrimp, not such a great idea. I recently discovered that they can be aggressive, and require 5 gallons of water per ghost shrimp in order to make their own territories. They also can eat smaller fish.

An idea...leave the ghost shrimp and the white clouds in the unheated 2.5 gallon...and get a 5 or 10 gallon tank set up (with a heater!) for the guppies. Even in a 5 gallon, you can have 3-5 fancy guppies safely and happily.

I fully believe your guppies color issue is from the lack of heater in the tank.

Keep me posted, and let me know what you decide to do, or if you need help figuring out other solutions. :)
