Pop Eye?! Help Wierd Guppy Symptoms

[plasticglasses]

Before I say anything the quality of my water is perfect and my tank has been fully established, 2 of my guppies are having wierd symptoms, compared to the other guppies there eyes look dialated when viewed from the side there eyes aren't protruding, I have been treating them for pop-eye with maracyn, and doing 20% water changes daily (there are 3 pregnant females i've been trying to encourage) i thought they were better, but what i noticed is when the light in the tank is off for about 30 minutes there eyes go back to completely normal then almost 5 seconds after turning the light back on the silver ring around the black part of the eye turns black and the eyes on my two guppies look dialated again. I've searched the internet disease list for fish and the closest thing i came up with was pop-eye but there eyes aren't protruding if they are it very hard to notice and if its being caused by parasites growing behind the eye, why would the light affect it........ please help...... here are some pictures from before the light is on and after

It's not popeye but you can get eye parasite like eye flukes, is there any white specs on the eyes, also the gills look abit red behind the gill flaps, do the gills look red and inflamed, also any laboured breathing or flicking and rubbing on objects.

Not the writer of this information below.

Eye Flukes (a.k.a. Eye Cloud)



Symptoms:

Fish with this condition will have white specks inside the lens of the eye. This can lead to further damage, ranging from cloudiness of the eye to rupturing of the lens and blindness. In severe cases the eye may actually be pushed out and removed from the socket, leaving the fish eyeless.



Cause:

The larval stage of digenetic fluke parasites, such as Clinostomum, Posthodiplostomum and Diplostomum spathaceum. The parasite lodges in the lens, humour or retina of the fish’s eye. If present in large numbers, severe damage can occur. Minor infestations may go unnoticed. The life cycle of these flukes begins when fish-eating birds and other animals ingest fish infected with the parasites. Once ingested the parasites mature in the intestines of the host animal where they produce eggs. The eggs are then deposited into the water where they hatch and infect the livers of aquatic Snails. The parasites then develop into a second and third larval form before leaving the Snail to seek out a fish host. This type of parasitic infestation is most common in wild-caught fish and fish kept in ponds.



Treatment:

Treatment with Copper or Organophosphorous antiparasitic remedies have proven most beneficial. Prevention, however, works best. This entails avoiding any obviously infected fish, discouraging fish-eating birds from visitng your pond, and remving any snails from the aquarium or pond to end the cycle of infection (so as to interrupt the life cycle of the parasite).

the gills aren't inflamed no white specks and is acting normal, the only problem is a little bit after the lights are on in the tank two of my guppies eyes get dialated looking but it goes back to normal when the lights are off a little bit. I have seen no diseases linked to the lighting in the tank..........

I wouldn' worry about it, are they wild caught fish as that could be the reason not used to tank lights.

it's a regular female guppy and a fancy guppy i purchased from walmart(ugh) i knew they kept there fish in poor conditions so they are in a quarantine tank, i wasn't going to introduce them to the main tank for about a month straight of good health, but it doesn't seem healthy

 

[WILDER]

It can take them a while to get healthy when they have been kept in poor water quality, a good varied diet of frozen foods and veg, plus there flakes, should fetch them to good health in leaps and bounds if nothing serious is wrong, the eyes could be because they are not used to tank lighting.
