Don't know why it's not on here but zebra danios will kill neon tetras. I have had fish for 15yrs & every time I put zebras in my tank they kill my neons. It's happened 6 differnt times. Has anyone else had this problem?

    I have 4 glofish and one zebra danio. I recently added one glow light tetra and it was very calm. I thought these fish would get along, but now two days after I buy the tetra; I come home and my glofish had killed my tetra.

    I have had the same experience. I have introduced neons to a community of danios and bloodfins twice, and the neons disappeared within a two or three weeks. I would advise against trying to house them together.

    eeee really I have not got them yet but I am getting soon. Do the zebra danios eat the neon tetras I have them :(

    I'm having that same exact problem! How do I stop it from happening?!
  • w. r - 2011-01-16
    Yes, I first started my new tank with 1 zebra danio and yesterday I bought a neon tetra soonest I put it in the tank the zebra started to chase him, I return it to the store and came with another zebra and the biggest one started to chase the small zebra, are this fish crazy or what?, I think that they might need xanax.

    Wow, That's weird. I have 18 neon Tetras and 6 Zebra Danios. They get along fine and it's been 8 months. The Danios only seem to harmlessly bother each other. Chasing each other in a big circle around a rock.
    Thanks though. I'll keep an eye on them.

    Hi I would just like to say that I disagree with you, as I have danios and tetra living together, and have had no problems. They are highly compatable. Mine have been living together for over 6 months and are very happy together,

    We have had 2 danios in with our tetras for over a year and there has been no problem. The male danio chases the female and the tetra very aggressively, but that is all.

    I have 8 big zebra danios and I had 24 neon tetras, I now have 7 neons left! I had never thought of this before, but they are the only fish big enough to eat the neons, so it has to be them! Damn it they have decimated the neons, going to have to sell the danios I think.
  • Tanya Altice - 2012-02-20
    When I had my tank I learned that a) you have to provide schools for each fish danios like at least 5 like fish in the tank. Neons like even more than that. b) generally you buy neons very small! and and small new fish don't do well with established bigger fish. So I would say get a small 5gal tank and set it up for a school of about 8 neons and let them get bigger than what you normaly buy them. Then put them in your tank with the others and give your danios some friends to play with so they will leave the others alone. Also neons aren't very hardy. I have had several trips around and around with neons where they simply die within a week of buying them. So be prepared to spend some time building a good school of neons.

    I have to disagree with that. I had group of 5 zerbra danios and they never had bother the neon or the rest of mine tetras. Yea, a little bit of fish nipping but they play tag with mine rams lol

    Oh, really? I didn't know that. Do danios get along with goldfish?
  • Jeremy Roche - 2012-06-26
    Zebras Danios are famous for stressing and harrassing other fish.  They are small but they are very fast swimming and in groups this can be taken as aggressive and make others stressed.  Neons are easily stressed.
  • aiden - 2012-06-26
    i just put 10 neons in my tank with my 2 zebra danios, (there were 3 but the others bullied the smallest until it died) 3 hours later the first neon is dead and they're trying hard to single off another!

I have 4 of the little guys and they are great fish. they will some times split up from their group and swim around in a loosely formed group. I might add 2 or 3 more to see if I can get a better schoaling behavior. great fish, fun to watch. Enjoy your danios!

Very interesting, I just started my tank, I have 5 danios, one week into the cycle they also went crazy doing the fin nipping thing, but have stopped and only chase each other now. I have since rescued two pink danios (glofish) and introduced them to my tank with no problems. However, after the cycling period I want to add 4 cory's, 1 siamese fighter and 2 platies? My tank is 57L, any comments/advice?

    Ammonia spikes will make the fish act out if tank is cycling.
  • Tate - 2012-08-22
    I have a 10gallon with otocinclus, a green Cory, and zebra danios all doing fine. I tried adding my sisters fighting fish and he kept chasing and trying to eat the danios. I wouldn't reccomend the platies, due to previous comments about the neon tetras

I have heard about them being agressive and that they eat alot, but i found that out after i had bought him. It seem to eat a lot of tubiflex so i let him eat alot of that. But he doesnot eat much of the flake food i give him. I have an oranda and 2 platties in my tank as well as him though 1 of the platties is in a breeding net as she is pregnant. I have seen no signs of him showing agression to the others. Will he get more agressive soon or what? I do not know what to do! Plz help!

Not so. I have Zebra Danios and they do not even bother the Neons. They do not bother any of the other fish not even the Guppies. That person may not feed his Danios enough food. You should feed them several times a day in small portions.

    Zebras Danios are pretty peaceful. They do nip fins at times but other then that are very easy going little fish. Their fast group swimming can however stress other fish out.

Is there a certain time in the year for which I should set up a zebra danio breeding tank and will I be able to see the eggs or fry?

    The answer to your qustion is you will be able to see the eggs and fry
    and acording to where they live it would probably be a good idea to mimic there natural enviorment so they feel more used to there surroundings.

    Here is a tip on zeabra danio breeding one is make sure its a spacious tank this is where they feel most safe.

    your welcome

How much do you have to feed them per day ?

    A lot, if you don't feed them enough they will defend any available food on the bottom of the tank and kill any weak counterparts for food, which I have noticed by losing a fish per weekend we have been away.

I HAD 5 Zebras, yes they are flashy, energetic, and fun to watch. I recently read a comment about them killing neon tetras and didn't believe it. The last 3 weekends we have been staying away for a night and each Saturday we returned home I had a dead fish. The first being a danio, the second being another danio, and this last saturday, my biggest female neon.I noticed that the Zebras are VERY aggressive feeders and they consume more than any of the other species in my tank. I have concluded while we were away everyone was picking the bottom of the tank and the Zebra's survival instincts said to defend any available food. Keep your Zebras fed, fish-heads!
