It iscarassius auratus. You can't tell untill they are older but females are usually fatter than males.

You'd see the difference in gender by looking at their vents, females have a slightly protruding, rounded one, while males have a oval concave one. You can also see it when they'll be in "breeding mood" as the male will develop little white spots on their gill covers and pectoral fins and the females will get chubbier as they fill up with eggs Wink

They look like common goldfish, simply.

And they're most likely "turning black" because they're being poisoned by ammonia. How big is the tank you keep them in? How often do you change the water and how much? Do you have a test kit to test pH, ammonia, nitrite and nitrate?

Hi Nossie, thanks for that, I change the water every three days and we wash every thing through with clean water Stones, Filter etc.

I don't know the size of the tank that we have but we put in 8 Ltr of water together with (tap safe) 1 cap full to 2Ltr.

No we dont have a test kit as we don't know where to find one as we have looked in our local pet store Smiley

The black is probably ammonia burns. Goldfish constantly create ammonia and if your tank is not big enough and not cycled, they are getting ammonia burns and being poisoned.

thetoonforeva: You mean that you wash the filter under tap water every three days?! You're killing the beneficial bacteria that would protect your fish against the ammonia. You should always clean it in a bucket of tank water, it's the chlorine in the tap water that harms the bacteria.

Are you saying that you change about 8 liter of water in the tank at a time or what? If you're saying that the tank is a total of roughly 10 liters, it's not even enough for half a goldfish. If you want to keep these three healthy and happy (they will grow up to 12 inches!!) you need a tank that gives 40L per goldfish, minimum. I'd go for a 150L tank. Please go have a look for a cheap, nice tank for these babies asap!

You could always order a test kit online, most people on the forum use API test kits.

As I look closer on the photos, your fish have obvious ammonia burns, the tails are blackened and slightly torn :/ They're clamping the fins as well, a sign that they're definitely not in good shape.

Hi, Thanks for that info. I will go out ASAP to get another tank as I was going to later on as I want more fish anyway but this has put us into fastfarward to buy a bigger tank.

Thank you all very much

Good. While you're at it, buy a book or two about fish-keeping Wink They're wonderful as references when setting up a tank, what kind of filter you need, how the nitrogen cycle works etc. In case your fish would start showing symptoms of illness, the most common diseases are also pictured with suggestions for treatments.

Note that if you want goldfish, CALCULATE how many fish you can keep in your tank, 40-50L per goldfish, nothing less!! The filter needs to pump 10 times the amount of water in the tank, anything smaller won't keep up with the waste of the goldfish. (Example: You buy a 200 liter tank, the filter needs to pump 2000L/h, the more the better.)

The new one probably carried a disease with him and contaminated the tank.
You have to quarantine all new fish for at least 3 weeks.
