Animal-World Information about: Giant Danio

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

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

When i began my aquarium experience several years ago i was as naive as the come i had a 10 gallon tank with a simple H.O.B filter gravel and 2 plants and which was home to a 4 inch baby lake catfish i caught (again naive) i thought it would be a good idea to get him some friends so i added 3 tiger barbs 3 giant danios and 2 red tailed sharks thinking 10 gallons was sufficient i soon found out this was not the case. I proceeded to buy a 29 gallon tank and set it up and add the fish to there new home within 24 hours obviously I had never heard of nitrogen cycle let alone new tank syndrome. so one by one every fish died. that is every fish but the giant danios who also now that they had there own tank proceeded to have baby's so I am convinced that they are an excellent fish for beginners and experienced hobbyist alike. Ps let it be known i have come a LONG way in 3 years.

    That's a great story Tanner! I'm glad you never gave up, and your fish will give you many years of joy.

I have a 190-L freshwater tank with two African featherfin catfisn (Synodonts eupterus) and two jewel cichlids (Hemichromis guttatus). All of them are between 4-6 inches long, and I keep the tank at 27*C and a pH of around 6.3. It is well-planted, with Amazon swords and bunches of Java fern on bogwood. There is black sand as the substrate. For many months now I have been trying to find new fish for the tank, but I have found none that have survived for more than a few weeks. The jewels breed regularly and, during spawning, often attach the Synodontis, but other than that there has been no problems between the cichlids and the featherfins. Other fish I have tried include pangasius catfish plecs. I have considered trying African peacocks, but I am concerned about pH being too different for them. Right now I am thinking about giant danios, since they seem large and pretty robust. Would these be suitable tankmates?

    From the size of your tank and fish, your almost at about the right stocking level. But because your tank sounds to be well established, that could be pushed a bit. However the Jewel Cichlids are very aggressive, especially when breeding, and aquarists say no other fish can survive with them. Giant Danios are hardy and fast but they need a school, around 8 - 10 fish to be happy. Not sure how this will work out, might be better to keep the Jewel's as a species specific setup and do a community in another aquarium.

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

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.
  • Jeremy Roche - 2012-09-01
    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.
