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.
  • caity - 2010-05-24
    eeee really I have not got them yet but I am getting soon. Do the zebra danios eat the neon tetras I have them :(
  • lps - 2010-07-25
    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,
  • Anonymous - 2011-10-18
    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.
  • Kim - 2011-12-01
    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.
  • Alonzo T. Fells II - 2012-04-15
    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
  • Maeve - 2012-05-20
    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!

Hi!

I love your site and has many different species!

I had two Pangio Kuhil loach's that were doing fabulous, I bought another two yesterday and now three are swimming like they have something after them, they swim quickly up and down the tank, the fourth just lies around.

Mine don't seem to be nocturnal as they are swimming all day.

What I am wondering now is are they upset that two more were added or perhaps trying to harm each other, including the one that lies around?

The other two never did this, as said, the three are swimming up and down really fast and they do this until they tire.

I read up on something about catfish and that they get confused but didn't understand it all.....I don't know if my two catfish are called catfish, mine are bottom feeders and maybe an inch long max.

Any help would be appreciated, they were added to the tank just yesterday, if they were just getting to know each other or were out of sorts and confused, this should have topped.

    The 2 fish you saw swimming up and down the tank might have a been a act of mating. Expect to find babies loaches soon!
  • Jean - 2011-11-09
    I've seen behavior like this called a "rain dance". I'm sure it's attributed their mating being brought on by rainfall like other fish in their native region if this is correct then a waterfall style filter may be simulating rainfall and bring on this behavior. I have had kuhlis for a few months now and I recently added 4 more bringing a total of 9. They are active all day long and exhibit his behavior as well as far as I can tell it's harmless. They won't breed until they reach sexual maturity which can take as long as 2 years but usually is around 18 months. In large numbers they like to lay around each other in the open all day and often play with each other. Don't worry if your kuhlis are acting like everyone else's their behavior has a lot of contributing factors including other fish in the tank, cover and filtration. The more hiding places you give them the more time they will spend out as they feel safer. There isn't a lot of comprehensive info about their behavior and breeding info is scarce. They have some very odd behaviors often being called foolie loaches because they like to stress out their owners by playing dead. Don't be surprised to find them hanging off plants they love to climb. For now I'm trying to document their behaviors and figure out causes. Most people will try and compare their behavior with other fish species but this can't really be done. Fish behavior is diverse for every type. Don't let people scare you by telling you they are under oxygenated I have two air stones running a lot of oxygen and mine still "rain dance". Best I can say is try to figure out what your tank conditions would be replicating in their natural environment and you might be able to figure out their seasonal behavior patterns. I'm rambling a bit. Hope I helped.

    Despite good water parameters, triple zeros on the cycling ( 0 ammonia, 0 nitrite, 0 nitrate) in my planted sand ten gal with just six pepper cories, my two new black kuhli loaches kept doing the circles too and got me worried. I knew they school like cories, but more research shows I should get more. Thinking of buying three more. Thanks for sharing. Do you still have yours and how are they doing?

My daughter just won 5 common goldfish at a local carnival. Are they okay overnight (fish stores are closed), what size tank should we get, and are they okay until morning without a tank? The only options we have are a 1 gallon betta kit and a 10 gallon aquarium (we don't have the water or conditioner for the 10 gallon)?

    Ok, first of all you need more than a ten gallon tank. Number two, look on this website if you need help. It works wonders for me. thegoldfishtank.com

Hi I have 8 hardy common goldfish, and they are juvenile fish. Can I keep them in a 10 gallon tank? Since they are still small. I know that they poop a lot and yeah I have to replace the cartridge every two weeks. Me and my dad are caring for the tank, later on we will buy a 60 gallon aquarium at the pet shop. How many gallons does one goldfish need? How big do these kind of goldfish grow? Do I have to build a pond? My tank has a hanging power filter. I wonder if needed an under gravel filter. I have colorful rocks and a bamboo, I know 8 goldfish need a lot of space so I don’t want them to live with lots of decorations. I’m the one who always cleans the filter. My dad always does the water change. Oh yeah, and I need to know how to clean out the fish tank, because my dad usually takes out all the water with a siphon, so I did some research and it said to siphon out 32 cups of water or 20% but I don’t know. So please tell me some steps. I feed my goldfish “Goldfish Flakes” , and that’s all. I tried feeding them “Goldfish Quick Grow Pellets” but when I threw some in, they ate it but then they spitted them out. I don’t know if they are the right age to eat them yet. What else can small goldfish eat? I don’t know if they can eat live food like water fleas or bloodworms. Please give me a good reply thanks!

    My goldfish wants to eat me alive when it sees me :) I heard they are very social.

    That's nice and all but I wouldn't do that. Fish Have a slim coat that protects them from illness. And by peting your fish you can be harming them.

Hi. I have a bad history with goldfish. I saw a 1 gallon goldfish kit at walmart for about $10 with just about everything you could need for a freshwater fish in an unheated, unfiltered tank. I was wondering if this tank would be sufficient for 1 or 2 common 28 cent goldfish, assuming I cleaned the tank once a week because my schedule is tight. If someone could let me know about this it would be greatly appreciated, thanks.

    Nope. The goldfish can not live in an unfiltered tank and certainly not a 1 gallon! You would need at least a 75 gallon tank with excellent filtration no heater thought.
  • Alfred Minio - 2012-06-04
    General rule of thumb is 10 gallons a fish(with goldfish) and they defiantly need a filter.
  • Yelena - 2012-10-04
    I have a baby goldfish in a 1 gallon round fishtank for two months now. So far it's doing absolutely wonderfull as long as i change 3/4 of the water every morning with tap water. It takes only two minutes, so it has become as routine as to brush my teeth. I keep tap water in a bowl overnight before adding it to the tank, so it is the same temperature. My fish is so energetic, and social, and growing that i invested in a 20 gallon tank, and planning to buy another goldfish to keep it a company.

I have had my fish for a couple months now and lately he has been freaking out and it looks like he is going to jump out of his bowl. I change his water about twice a week. Does anyone know why he is freaking out?

    Use some test strips to test amonia.  Sounds like amonia spikes.
  • David Brough - 2012-11-20
    It sounds like you may be changing the water too often and too much of it. First, make sure you use chlorine remover when you change the water. Second, get a small sponge filter or other biological filter like an under gravel (even gravel and plants would help as long as you don't thoroughly clean them too often). Once you have a biological filter going, only do small water changes like 20% per week. Also, if you put a plant or other decoration in the bowl or aquarium, the fish may feel safer. Check out 'Cycling Your Aquarium' for an explanation of how to get a biological filter started.
  • Anonymous - 2014-06-03
    Ok, dude. First thing when you say bowl I hope you don't mean a 1-5 gallon thing. For goldfish you need way bigger tanks. Commons can grow a foot long on average. And number two. Two times a week? Even for a fish tank maybe once a week would do good. And if it is in a bowl, it needs a filter too. Best bet get a tank. And another goldfish too. Goldfish get lonely too.

I got 4, 2 centimeter long common goldfish, and one commet goldfish 2 centimeters long too. my sister had hundred as feeders so lil babys. I have a one gallon goldfish bowl and i saved these lil guys. i feed them differents things from time to time so they get what they need; flakes, pellets, blood words, shri,p things for em. they seem happy and healthy, no ick, nothing i can see. They aren't competitive and swim around the whole tank. they seem happy but will the small tank kill them? i heard they grow to tank size and theyre tiny young ones. so will that be fine?

    They will need a larger tank, the rule of thumb is 20 gallons per goldfish. You will have to get a larger aquarium and should include a filtration system. See the information in the article above on how to take care of them.
  • Anonymous - 2014-06-03
    I agree, these fish you said you saved need a way bigger tank or fish tub.

although beautiful and hardy...My suggestion for stocking levels is 1 fish per gallon of water. Also, these fish have the most amusing habit of rummaging around in the substrate, by working gravel in and out of their mouths searching for anything edible.These are hardy fish which can tolerate a lot, but please dont use that as an excuse to mistreat them.

    1 gallon per fish is not sufficient it must be at least 15 gallons per fish.
  • Anonymous - 2014-06-03
    One gallon of water per inch of fish is better for healthy goldfish.
  • Rachel - 2014-06-04
    We tend to use the rule one gallon for every inch of fish. For a five inch fish you need five gallons of water, a three inch long fish needs three gallons of water, and three one inch fish will also need three gallons of water. For all of these fish together in one tank the bare minimum would be 11 gallons.
