I had 5 baby fantails. I've lost one.. I thought it had swim bladder by the time I returned back from the pet shop he was dead.. Now another is going the same! Just as I returned my black tip one started acting the same.. floating, not eating! I thought maybe fan rot? as he's had it 4 days!!! I've tried everything!!!! The shop said they r very small and I really shouldn't of been sold them this size! They r about 2cm full length.. My water is fine shop tested it also.. I've given peas and not fed for 2 days.. the salt thing I just don't even know what is causing the problem to fix it!!! The shop think it's as they r so young.. but all fish were once this young...

Just got a fantail for my 17 month old, but everything I read says they are cold water fish and it is usually like 75 - 80 degrees in his room. I am wondering if that is ok.

I love my Fantail, he/she is definitely one of my favorites, I have quite a collection of fish going right now, but my Fantail is my favorite to watch and he/she is just so gorgeous! This site was very helpful. I didn't know much about them. He/she will get very good goodies in the near future!

    You are changing the water every 12 hours? That will cause a lot of stress and not give the tank time to adjust.

    Don't change the water every 12 hours, it will stress the fish out!

I have a Orange Fantail Goldfish and a Calico Fantail Goldfish. My Orange one is the oldest. I have been watching them and my smaller one chases my bigger one. Now the bigger one is at the bottom of the tank. He/she is still breathing fine just wont leave the bottom of the tank. The smaller one has been under the bigger one. Then leaves to eat then goes back....should I worry? Do anyone thinks there's something wrong with it?

    This happens sometimes when they are constipated. If it is try feeding it a frozen pea. This will get its insides moving again if that is what it is.

My fish is lying on its belly and has breathing problems. He's a little fighter though, but I dont know how to cure it and I need to know.

    Is your fish still eating? He might be constipated and need a couple of cooked peas (shell off to help him out hope this helps a bit :)

    Have you checked your water levels? How is the ammonia level? Is there enough air movement in the tank? Could be a simple fix if you jump right on it.

Hi , my little sister bought a fantail and I was just wondering how can you tell if it's a male or female and is it safe to be in a tank with a couple tetris and a small blackmoor?? Also, the tank has a food area and it has been putting the pebbles up under the food bit and has aslo been spending its time in that area does that mean it needs a partner??

    It's hard to tell the sex of a goldfish unless it is in breeding mode, where the female is generally fatter while the male is slender, also the male may have more pointed fins. Your goldfish should be fine with tetras and the other black moor goldfish. As far as its habit of playing with the pebbles and spending time in the food area, those things don't indicate it needs a partner. It should be fine by itself, but adding another is okay too as long as your tank is large enough and has enough decor to provide places of refuge for each of the fish.

    OK thank you
  • Jeremy Roche - 2012-02-27
    One thing to keep in mind is that Goldfish produce a lot of amonia into the tank that could harm the tetras. Depending on type of filter and tank, I would get some amonia removing bags or pellets.

    Proably nothing. Possibly the white one is a female and the other two are males. Unless you see agression - don't worry.

    When the female is carrying eggs - somehow the male knows this and he will start to push her or push at her abdomen until the eggs are released. He will then fertilize the eggs. How long? That depends on the age of your fish. They will figurew out when.

I bought two fantail goldfish yesterday and the white one is constantly chasing the red one. I'm worried the red one might die from stress. Any advice?

    Just watch them and give them a few days to settle in and determine who is the BOSS. Things should quiet down. Are there decorations etc for them to hide if necessary? If not just put a coffeee mug in there and lay it sideways.
