Guppies fins

[CraigDalton]

Hi everyone,

I have got in my tank 6 male guppies, a pleco, some rummys and some neons and I also have I male crowntail betta.

My problem is recently I have noticed on three of my male guppies the tail fins have started to disappear. Only small amounts but it seems to be whole sections down to the base of the tail, its not like small nips like it's been nipped by another fish. I do have the betta which I think would be the only problem if that was the case but honestly they never ever bother with each other they never go near each other or anything so I believe my betta accepts them. They are however very active with one another but could they cause this? I've never dealt with fin rot but I'm not sure it could looks like this but then again I don't know. Could anyone give me any answers and will their tail fins regrow?

From personal experience... They probably won't regrow. A few of my guppies have these kinds of slits and tears in their tails, and haven't seemed to be growing back yet.

The water looks milky cloudy.
How long has the tank been set up for?
What is the ammonia, nitrite, nitrate and pH of the tank water?

How long have you had the fish?
Have you added anything in the 2 weeks before this started?

How often do you do water changes and how much do you change?
Do you gravel clean the substrate when you do a water change?

What sort of filter is on the tank?
How often and how do you clean the filter?

-------------------
DO THE FOLLOWING
Wipe the inside of the glass down with a clean fish sponge.

Do a 75% water change and gravel clean the substrate every day for a week. The water changes and gravel cleaning will reduce the number of disease organisms in the water and provide a cleaner environment for the fish to recover in.
Make sure any new water is free of chlorine/ chloramine before it is added to the tank.

Increase surface turbulence/ aeration to maximise the dissolved oxygen in the water.

Add some salt, (see directions below).

-------------------
SALT
You can add rock salt (often sold as aquarium salt), sea salt or swimming pool salt to the aquarium at the dose rate of 1 heaped tablespoon per 20 litres of water. If there is no improvement after 48 hours you can double that dose rate so there is 2 heaped tablespoons of salt per 20 litres.

Keep the salt level like this for at least 2 weeks but no longer than 4 weeks otherwise kidney damage can occur. Kidney damage is more likely to occur in fish from soft water (tetras, Corydoras, angelfish, Bettas & gouramis, loaches) that are exposed to high levels of salt for an extended period of time, and is not an issue with livebearers, rainbowfish or other salt tolerant species.

The salt will not affect the beneficial filter bacteria, fish, plants, shrimp or snails.

After you use salt and the fish have recovered, you do a 10% water change each day for a week using only fresh water that has been dechlorinated. Then do a 20% water change each day for a week. Then you can do bigger water changes after that. This dilutes the salt out of the tank slowly so it doesn't harm the fish.

If you do water changes while using salt, you need to treat the new water with salt before adding it to the tank. This will keep the salt level stable in the tank and minimise stress on the fish.
