Sick Angel Fish

Hi, I have something a bit strange. I have a 40gal tank with two Angels (silver black stripes) black neons, cardinals, other small tetras and a plecky. Every so often the smaller Angel appears to get white spot. White spots appear all over it's body as raised bumps the size of a pinhead. The strange thing is it is the only fish in the tank affected! The other Angel did get it but seems to have "outgrown" it as it is nearly twice the size of the small one (it is the dominant fish). The Small fish is about 2" top to bottom the larger fish is more like 3". I have tried several white spot treatments thinking it white spot, but it seems to just go away on it's own. I suspect some type of parasite but cannot understand why all other fish are immune. This has been going on for nearly a year.

Thanks
Mick

How many gallons is the tank.
What are your water stats in ammonia, nitrite, nitrate, and ph.

Is sounds like whitespot if the spots are the size of a grain of salt.
Does he flick and rub.
Very odd if it's been going on for over a year.

Read this thread to see what you think.

I think this is the fish we are talking about in another forum about a blue ram. Any chance of a pic? If the spots are tiny then it's unlikely to be Lymphocystis as mentioned in the other thread.

Hi, the white dots happened on my rams, too. Here you go, have a look.

it doesn't appear to be whitespot due to the shape of the white bits. Whitespot is actual round dots, whereas some of the marks on your fish appear long and slender. They could be a type of fish lice but it is a bit hard to tell from the pics.

You could try treating them with Flubenol or Praziquantel. Flubenol is a general wormer but also kills of a lot of flukes. Praziquantel treats tapeworm and various flukes.

Use 100mg of Praziquantel per 20litres of tank water. Do a partial water change 24-48hours later. Repeat the treatment after a week, followed by another water change.

To work out the volume of water in the tank
measure Length x Width x Height in cm
divide by 1000
equals volume in litres

When measuring the height, measure from the top of the gravel to the top of the water level. If you have big rocks or driftwood in the tank, remove them before measuring the height.

Before you treat the tank do a 50% water change and complete gravel clean. This will reduce the gunk in the tank and allow the medication to work more effectively. It will also lower the pathogen count in the water and mean there are less nasties around to infect the fish.

Make sure any new water is free of chlorine and has a similar temperature & PH to the tank.

Remove carbon from the filter before treating otherwise it will absorb the medication out of the water.

increase aeration/ surface turbulence to maximise the oxygen levels in the water during treatment.

Flubenol will have different directions, so you should follow whatever is on the container.
