Animal Stories - Giant Danio

Animal-World Information about: Giant Danio

The Giant Danio is aptly named, because it is two or three times the size of the other danios!

I have discovered my danios like to eat frog eggs and worms.

Hi! I'm really new to being an aquarist, and I decided to bring two giant Danios home with a (cleaned) 10-gallon setup I bought from a thrift shop for cheap. I do have a question about feeding in much is a 'little amount'? To err on the safe side, as I've heard of fish dying from overfeeding so I give them three small meals of around...four large flakes equivalent. Maybe somewhat less than a pinch. Am I giving them enough food, or am I giving them too much? This is my first time and I really want it to be right. Thanks for the help!

    It sounds like you are doing just fine feeding your fish! I wouldn't worry about overfeeding them too much, as long as you do regular water changes. One pinch 2-3 times a day is a good amount.

    To start off, be sure you feed a variety of food including fresh chopped veggies. Also a 10 gallon is way to small for these fish. Even one or two. With only having 2 you will quickly notice a dominant fish in the hierarchy whom will most likely kill the other one. You need a group of at least 5 or 6 at minimum. 90 gallon cichlid community tank 75 gallon giant danio species tank

I've had my giant danios for over 10 years. They are in a 15 gallon high tank. I keep the water at 7.0 and tempature at 72-74 degrees. I only feed them flake food and sometimes frozen blood worms. I only feed them once a day. Is this unsual for them too live this long?

    From what i can find out - they normally say the average life expectancy is about 5 - 7 years so you are doing good.  Congratulations.

    Those are great fish and yes it is a bit unusual for them to live that long.  Great job on that!!

    I had the opposite problem my giant danio was chasing my roseline shark so I got two more roseline sharks and now all of my danios and roseline sharks swim together. I dont know if that helps but it worked for me :)
  • Jeremy Roche - 2012-04-02
    You can also try re-arranging the tank to force the barb to find a ne territory. Both of those fish should really be in a school.

I have 3 giant danios and 3 roseline sharks in my 55 gallon with other random fish like yoyo loach and pleco. I love my danios they are so lively it's fun to watch and good to hear about other peoples tanks :)

Very cool. I have a fish tank with just 3 small zebra danios right now. Feel free to check out the live stream of my fish tank. If the stream is black, it's because its night time here, try back M-F 7am -7pm.

I am hoping to add a Giant Danio or 2.

I have a school of giant danios in with my piranhas. I have 3 red-bellied piranhas and 6 giant danios in a 90 gallon tank. They're fast enough that they're safe, and they do really well in there. I just found about 300 fry in there, yesterday, so I've moved as many fry as I could catch to a separate tank.

We have just purchased two Giant Danio's. After two days having them in our tank I have just found 1 of them floating yesterday and another floating today. The ph is 7.0. It's a Cold water tank and cleaned regularly. We are trying to find out what happened, as also they were healthy fish. We have others in there that are healthy also.

    From personal experience - my Danios love my wamer water temperature of 80.2F and do really well. Perhaps your tank was too cold for them.
  • Jeca - 2010-04-18
    Cold water tank huh? 70 degrees and higher for these fish. Does your cold water tank maintain a consistent temperature? That might have been your problem.

    I had the same thing happen, I had to add aquarium salt and baking soda to my tank. It made an immediate difference. My fish had lost most of their color and were constantly moving their mouths before they passed away. I ended up with 2 of my 5. Find a test stip that does GH and KH to see if you need salt or baking soda.

My small batch of giant danios has seemingly adjusted well to a vertical 33-gallon tank, despite not having as much room to school side to side as they'd ideally like. The tank is a little warm for their tastes by the range listed here, more like 80 degrees F than 75, but they remain active and engaging and have shown no health problems.

These really are among the most engaging truly peaceful fish I've kept. They immediately learned to react when I'm near the aquarium lid, and their eating is a little feeding frenzy of darting bodies hitting the surface. Despite the constant active swimming, they've never shown any obnoxious interest in the fins or movements of anyone else; Gouramis, for example, don't get their feelers nipped.

In general, for me these have been easy to care for and quite enjoyable fish. They're beautiful, and also inexpensive.

I have six Giant Danios with four Dwarf Gouramis in a 20 gallon tank. The Gouramis are not bothered by the Danios and the Danios have enough of their kind to keep them amused. I am very pleased with this combination. Cheers, TopCat james
