Hello, i am looking for some advice. I have noticed my male guppy has a few marks on his tail. Like a silvery whitish patch here and there. Is this fin rot, fin nipping or something else? Currently i have only 4 male guppies together in the tank. I don't want to dose him if not necessary with medicine. Only just recently got them. Thanks
Fin Nipping or Fin Rot on my guppy

The tail seems mainly intact suggesting it’s not fin nipping- I adopted a male which had a bit of a torn tail and the edges are much more uneven than that. I’d suggest you will be advised to medicate- to me looks like fun rot but I’m far from an expert
Need a clear picture of the fish.
If you are concerned about the white patch in the middle of the tail, that is not fin rot, which starts on the outer edge of the tail and works in towards the body. I can't tell what the white bit is and a clear picture should help.

I've had trouble getting a clear pic as hes a super active little thing. I have attached a few more. Hope that helps. I wasn't sure if it could just be a marking.

Hi i have a clear pic now i thinkno they don't help
take a bunch of pictures and check them on your computer. find a couple that are in focus and clearly show the problem, and post them.

not sure. it could be the start of a fungal infection.
add some salt, 2 heaped tablespoons of rock salt per 20 litres of tank water. keep salt in there for 2 weeks and see if it helps.
the salt wont affect filter bacteria, plants, shrimp, snails or fish.

Thanks, i will try that and keep monitoring. I have backup medicine too as just bought some king british disease clear and interpret velvet slime coat and fungal clear. Hopefully though it will clear up. I'm new to fish keeping and the tank is on the 4th week of its cycling. Only added the 4 guppies last week and been monitoring the water levels using the api master kit once in the morning and evening. Also doing a water change of 10% - 15% every 2 to 3 days and vacuuming the poops.
Ok thanks. I will do larger water changes and also, i noticed my small guppy today with white poop. Is this a worm do you know?

It is. I just had that happen to my guppies and it’s had rly bad impacts. I’d suggest buying some aquarium salts and some medication.
Fish do a stringy white poop for several reasons.
1) Internal Bacterial Infections causes the fish to stop eating, swell up like a balloon, breath heavily at the surface or near a filter outlet, do stringy white poop, and die within 24-48 hours of showing these symptoms. This cannot normally be cured because massive internal organ failure has already occurred.
-----
2) Internal Protozoan Infections cause the fish to lose weight rapidly (over a week or two), fish continues to eat and swim around but not as much as normal, does stringy white poop. If not treated the fish dies a week or so after these symptoms appear. Metronidazole normally works well for this.
There is a medication (API General Cure) that contains Praziquantel and Metronidazole.
It's interesting that API and the Californian government have listed Metronidazole as a carcinogen. That's a concern considering it was widely used to treat intestinal infections in people.
Anyway, if you use this or any medication, handle with care, don't inhale the medication, and wash hands with soapy water after treating the fish or working in the tank.

3) Intestinal Worms like tapeworm and threadworms cause the fish to lose weight, continue eating and swimming normally, and do a stringy white poop. Fish can do this for months and not be too badly affected. In some cases, fish with a bad worm infestation will actually gain weight and get fat and look like a pregnant guppy. This is due to the huge number of worms inside the fish.
Livebearers like guppies, mollies, swordtails & platies are regularly infected with gill flukes and intestinal worms. If the fish are still eating well, then worms is the most likely cause.
You can use Praziquantel to treat tapeworm and gill flukes. And Levamisole to treat thread/ round worms. If you can't find these medications, look for Flubendazole, which treats both lots of worms.
Remove carbon from filters before treatment and increase aeration/ surface turbulence to maximise oxygen levels in the water.
You treat the fish once a week for 4 weeks. The first treatment will kill any worms in the fish. The second, third and forth treatments kill any baby worms that hatch from eggs inside the fish's digestive tract.
Treat every fish tank in the house at the same time to prevent cross contamination.
You do a 75% water change and complete gravel clean 24-48 hours after treatment. Clean the filter 24 hours after treatment too.
Do not use the 2 medications together. If you want to treat both medications in a short space of time, use Praziquantel on day one. Do a 75% water change and gravel clean the substrate on day 2 & 3. Treat the tank with Levamisole on day 4 and do a 75% water change and gravel clean on day 5, 6 & 7 and then start with Praziquantel again on day 8.
The water changes will remove most of the medication so you don't overdose the fish the next time you treat them. The gravel cleaning will suck out any worms and eggs that have been expelled by the fish. Repeating the treatment for 3-4 doses at weekly intervals will kill any worms that hatch from eggs. At the end of the treatment you will have healthier fish.
