Unhappy panicking please help white spot

Hiya I have 25 litre tank with 3 harlequins, 3 neon tetras and one common plec. My poor plec was acting unusual recently swimming in the middle of the tank like hovering but other than that he seemed fine.

Now he has torn like fins and white spot!! Thing is I've been stupid and did a 50% water change and gravel clean last weekend and a 20 % change today and added the fin rot interpet number 8 before realising through the power of Google that it is secondary to the dreaded white spot!!

What do I do? Can I add the white spot treatment now after already adding the fin rot treatment to cancel it out and treat the real cause?

This is the first real outbreak I've had on my fish and my plec is my baby lol please hope someone can help.

I tested the water yesterday but with the strips I know you all dislike but it's all I've got at present.

PH < 6.4
KM 0-50
GH 250
Nitrate 50
Nitrite 0-0.5

Ammonia strips are stupid and don't seem to work properly but after leaving it for ages the strip finally changed from its standard yellow to a reading of 1.

I'm sorry it's not more specific.

Please help!!

Are you certain that it is not their normal white spots? Their spots can vary in size and number. Pictures will help. Also torn fins does not equal fin rot, fin rot is much different, if he tore his fin on something he'll heal up just fine with clean water. Try not to medicate unless you are completely certain (and hopefully others agree with you) that your fish need it. The more medication you use the more it becomes useless in the future; bacteria can become resistant to them.

I do want to note that common pleco's can get over a foot you have another home for him when he gets too big for the 25 liter (6.6 gal)?

I'm Sure it's white spot they are bigger than his normal spots and his skin seems rougher than usual. He has more then one fin affected and there is nothing he could have torn it on. He has been in the tank over 6 months and never had an issue before. He also had white gunk over his eyes but that has cleared with the water changes.

And I am aware he'll grow I've seen one full size and when the time comes I will purchase a bigger tank.

Yeah, that was probably Eye Cloud or Cloudy Eyewhich usually goes away with better water quality as you saw. If it is Ich you can simply raise the temperature up to 86-88 and do daily water changes, the high temperature will kill the free floating Ich parasites and the water changes will take it out. The water changes will also help his fins. Are you sure that none of the other fish are nipping him? That is also possible.

My harlequins and tetras are tiny compared to him and don't go near him so yeah I'm sure it's not then. I used to have mollies and they were buggers for nipping him which is why I had to get rid of them.

He does seem less spotty today, how much should I change I.e. 20% or 30%?

Thanks for your help

I usually say 50% to change but whatever you can do is quite fine, I'd say at least more than 25% will be good to do.

How is he doing now?

As Lilnaugrim said, if you have a fish that can withstand warmer water, then the easiest way to treat White Spot Disease (also called Ich) is to raise the water temperature to 30C (86F).

Ich is caused by a parasite (Ichthyophthirius multifilis). It can't reproduce in warm water. So by raising the water temp for a long enough period of time, it'll eventually die out.

The white spots that you're seeing are from parasites that have burrowed into the fish. While they're burrowed into the fish, they're protected from harm. They'll eventually fall off, but it takes a few days. So it can take about 5-6 days to see results using the heat method.

There are some strains of heat-resistant ich now, unfortunately. So if a temp of 30C (86F) doesn't work, try raising the temperature another degree to 31C (87-88F).

Here's some additional info about Ich, in case you want to know more.

There are 3 parts to the life cycle of Ich:

Stage 1) trophont - this is the stage where you see the white spots. The parasite has burrowed into the fish, where it's protected from treatment (which includes medications, salt and heat). So treatment isn't effective here. This stage lasts several days.

Stage 2) tomont - the trophont finishes feeding, and falls off. It's now called a tomont. Since it's in the water column, treatments (medications/salt/heat) are effective now - BUT only for several hours. It then forms a protective cyst around itself, so treatment isn't effective. Unfortunately, the organism is reproducing during this time.

Stage 3) thermonts - Several days later, the cyst bursts, and lots of new organisms go in search of a host fish. They have several days to find a new host, or they will die. Treatment is effective during this time.

So basically, you have to treat while the parasite is either in the early part of stage 2, or during stage 3.... Because the parasites go through three stages, you'll need to continue treating for at several days after you see the last of the white spots disappear. This is because the parasite is only visible during stage one. There are other parasites in the tank going through stages two and three, (but you can't see them,) so you need to continue treatment until it's gone through the entire life cycle sequence.
