A question about a black spot?
« on: August 22, 2010, 11:49:53 AM »

On the tip of my white fantails back tail fin theres a small black spot but im not sure what it is. I think it may be poo but i have no clue. Im just going to keep an eye on it and if it doesnt go away i will have to search more into the topic. Any ideas?

I also have another question about the behavior of my goldfish. I have an all white fantail named Pearl and an orange and white fantail named Patinka. Patinka always follows Pearl around and likes to nudge her why they swim. Pearl doesn't seem to mind but i keep thinking that its weird. Is that weird behavior or is it normal? Pearl also has a small patch of scales missing but i bought her that way thinking they will heal eventually. The pet store person said she will be fine? Any ideas?

Poo normally doen't stick to a fin. Usually it has got the same colour like the food they ate and the shape like tiny sausages  Tongue

I think the black spot you are worrying about can be ammonia burn and the missing scales due to poor water quality.
I mentioned about the Nitrogen Cycle in an other post replying to your question.

Take a sample of your tank water to the pet shop and get it tested, but write the results down, I mean the exact numbers and let us know. We can tell you then what may be wrong.

Don't be satisfied if the staff there tells you "..all is fine.." Get them to tell you the exact results and they should show you the water samples and the colour charts so you can compare too and learn how to read the test results as you may be able to perform those tests by yourself eventually
