I got 5 of the long finned pink ones recently and yea like everyone else has said these guys don't stop moving. In fact they move so much it's almost to a fault. They're not pulling out my other fish but they sure make feeding time a whole lot more livelier. They're also a great beginner fish as they are relatively cheap and beginners love to see movement. Suggested for any one in need of something to look at :D
I have six of these little guys and they make great fish for beginners and advances.
They are extremely hardy and also active, so they may not do well with slow/peaceful fish. Zebra's make excellent pulling fish, especially with timid fish who are too scared to come into the open. They will see the danios running about and feel more comfortable. Also, when first cycling a tank these are also ideal fish - though remember that cycling is hard on all fish even those who don't seem effected by it.
Despite their community nature I haven't found them to be good schooling fish, as they tend to spread out all over the tank. Mine swim top, middle and bottom (though mostly because I only have suckers on the bottom of their tank) and even whem my Ember Tetra's were in with them, they just swam every which way.
Some very nice danios to compliment them are the long-finned variety, which come in blue, yellow, and the zebra stripped and probably more that I'm not familiar with.
In an example of how tolerant they are to change; when my heater malfunctioned all my fish were toasted, even the pleco, except for the Zebra Danios. Not one of them died or fell ill.
I got 2 zebra danios and 2 leapord danios and added them to my 9 gallon with my two paradise fish. They are extremly active and enjoy swimming in front of my paradise fish when there having an argument. They were so active I couldnt name each of them so in the end I called them the fantastic 4. Great fish but I woudnt suggest them or any other fish as cycling fish because its cruel on them and you would be better of just adding the treatments and some live plants.:)
Zebras are great little schoolers who love fast-moving water. They are best kept in groups. Since the new genetically modified fluorescent GloFish came out I've been a complete sucker for them. For a while the green ones were only available online, but I got a couple from PetCo recently and they have nice long fins and just a wonderful dayglow color. Once I move the goldfish in my 30 gallon tank out into their pond I plan to fill it with GloFish and maybe some neons. I totally hate the practice of injecting fish with fluorescent dyes -- the GloFish carry the gaudy color gene to their offspring and keep it their whole lives. Very fun for new and old fishkeepers.
I had ten of these guys and they are fast schoolers that seem to stay mostly at the top of the tank, they may bother more timid fish and can be slightly aggressive at times, but they are a hardy easy to raise fish that stay small for a community tank.
Active? Try ADD of fish. Really good starter fish. These things can go through hell and back again. A buddy had 5 in a 55gal tank and they just spent all day swimming back and forth in the tank and all over. He just recently added substrate and since he really doesn't care about his $0.99/ea starter fish he just left them in. The water was pitch black and you could occasionally see a Danio braise the side of the tank, or nip at the top of the water. 2 days later the water settled and the Danio's were simming around like they were normally. It has been a week and they are still alive. They have also survived very harsh conditions where he would forget to close the window which is right above the tank in winter and the water would get veerrrrrry cold overnight. The Danio's and Black skirts were indistructable (had 5 black skirt tetra's as well).
i have a 1 1/2 gal live planted desktop hex with 2 of the questionably legal "gold-pink" danios, allong with a few fairly large cherry and bumble bee shrimp, chinese algea eater, and a Juli corydoris. A nice little get away when at the desk for hours! a mini chinese hang-on betta filter, 13w power compact, and paintball co2 system(convieniently plumbed under the desk) is all you need for a gallon of nature
i had six of these two died by getting sucked in the filter and then after that the other four terrorized my tank and then after that they began to hang at the top and steal all thefood, so i moved them and have had no trouble i just wish i hadnt bought these things for me they were a nightmare. i know a lot of people love the4m thoguh
2 of these and 2 Pico Catfish were my very first fish besides goldfish. these guys are super hardy when i was 5 I thought these things would live forever (i used to think all fish only had about 1-2 year lifespan and they lasted over 5 years before i sold them). Great Fish!
Oh man, I had seven regular little Zebra Danio, and as everyone says, they NEVER STOP MOVING. The coolest part though, is anytime I siphoned my gravel, which was largish pebbles, I had fry. Every single time, man. Ended up saving about 20 once, to see if I could raise them, and it was too easy. They're about 2 months old now, and were so fun to watch grow up.
Very hardy fish but i am considering removing mine as i find them just too hyper, chasing each other all over the tank all the time. For a super calm and peaceful tank as i hope mine to be they don't fit in.
A very, VERY hardy fish... they do jump so you need a cover on the tank. I bought 8 of these guys originally, I lost half to jumping out of the top within the first month. I had another one jump straight into the HOB filter I was running, and it survived there for two and a half weeks. I thought it had just died somewhere in the tank, but no it was in the filter, really thin and scraggly, but there. I put it back in the main tank, and it survived up until I sold those which were left. These are great beginner fish.
A very aesthetically pleasing fish, although they do not make the best of tank mates due to their boisterous behavior. They can easily out compete more timid fish for food. Good luck catching them in a planted tank.
These were the first fish added to our cycled tank. I'd read the liveaquaria entry on them (easy care, peaceful) and thought they'd be great for the first tenants. We watched slackjawed as they wasted no time after acclimation before forming a swirling ball of murderous fish, chasing each other all around the tank. We like them a lot, and they don't seem too rough on the other fish, but if someone were to invent an antipsychotic for danios that would be just fine.
very fun fish, considering i only ever had goldfish these three were so much fun to watch and i can easily tell them apart just by where they are in their tanks and their shape. they do look like they're rough with each other at times but its all play never a mark on them, they don't like hanging around and schooling together unless scared and they will make up their own little territories for each of them. not yet had them breed but don't really want to so no complaints. I've killed every other fish I've had so that's just a testimony to how good these three are :)
