We get neons by the dozens and we have to do it from time to time because they do not last as long as they should. Now I realize if we got the $4/each ones it would be more responsible, but the 50 cent/each ones allow quantities of 75 at a time. They do look so wonderful in large schools though. They share their 90 gallon heavily planted and filtered auto-c02 controlled tank with 9 Clown Loaches, couple pearl gouramis, dozen rummynose, handful of glasscats, handful of bleedingheart tetras, couple catfish and a handful of cories. Wish I could afford 75 of the $4/each ones! They are stunning.

Lovely. It was ironic that I did not have any interest in any Tetras before. I thought small fishes were unattractive and dies within weeks. However, I was wrong. They proved hardy and impressed me tremendously with their flashy colors. I have twelve of them, and it is interesting to see their colors flashing again after the lights were turned on after total darkness. They almost appeared colorless. I noticed they do eat a lot. Remember not to overfeed. Just because they are tiny does not mean you have to feed exactly the way you do for bigger fishes! DO NOT add in other bigger sized fishes (Plecos, etc) as Neon Tetras sleeps and rests at the bottom and bigger fishes will simply vacuum them in.

    They can be a bit touchy, sometimes they are very easy to keep and other times not. You're best bet is to put them in a well filtered tank without any other fish but with lots of plants, at least until you are sure they have adjusted. Then you could try moving them into a community environment.

VERY GOOD FISH, GOOD FOR BEGGINERS AND FOR EXPERTS. People say you shouldnt keep them with angel fish but you could. Just buy the neons in an aquarium and wait until thay get around 1 inch or bigger. Then go to the store and buy baby angel fish and put them together. Then the angels mouths would be small and they could not eat the neons, and when they get big they would have already gotten used to the neons. HAPPY FISH KEEPING!

I have recently purchased my first fish tank and these guys are not afraid of even my boistrous ramirez! They come right to the front of the tank and get along well with the other fish. I have a shoal of 6 individuals. They must be kept in shoals of at least 5.

    i only have 4 neon tetras left and they seem to be doing ok.....although they seem to take turns kicking one random fish out of the group every now and again.....

    I think your neon tetras are pairing off. It's good you can try breeding them if you want

URGENT! I bought 5 neon tetras and 10 guppys 6 months ago. Since i was a beginner then, i tend to wash my tank once a week due to my worry-ness that they die due to the bad water condition. I also feed them well with fish pellets twice a day. After a few weeks, my neon tetras died one by one showing no sign of diseases. They do get along well with the guppys so it was not caused by them neither. My water condition was still acceptable. Can anyone tell me what happen to them???:(

    Your guppies should be fine companions for the Neons, and it sounds like you are good at keeping up with the water conditions. Neons are a funny sort. They are quite hardy if they are happy with their home, but sometimes making them comfortable can be a challenge. I had the same experience at one time that you are having. But today I keep a school very happily in a 50 gallon tank that has lots of plants (both planted and floating) which helps subdue the light, and they've been alive for almost two years. They live with different types of tetras, hatchet fish, cory catfish, and even a pair of geophagus cichlids (Humphead earthsifters). So what's the difference... I think its lots of plant cover and subdued lighting. Abigger tank helps too, as in a smaller tank you may have to be more careful to make sure they have plenty plants to retreat in.

    What do you mean by 'wash my tank'? Do you have any biological filtration like an undergravel filter and are you maintaining it by not 'washing everything'?

I have 10 neon tetra. I have had them for 3 to 4 weeks. They are all doing awesome. I test my water at least once a week. To make sure the PH is around 7.2 and 7.6. The temp is at 76-80 degrees. But I have a 55 gallon tank and want to know what other fish can I put in except the tetras. Thank you for the good information on your web site.

    My brother had some tetras and they do really well with other fish as long as they're not aggressive and last 2 years!

    Do you have any other fish that require the water to be a base? If not, then your water should be around 5.0 - 7.0 for the neons.

    bcoz of costie disease treatment is to dip in the sol of kmno4 or methyl blue

    Sounds like you have neon tetra disease for which there is no known cure :( Most say to get them out as fast as you can to try and save the ones you can. If they start to feed on them they will all die. I had a whole tank lost, but a few when I went to a local Pet Store and it was passed to my fish of Many,many years! I was heartbroken:( Clean you tank well.Good luck.
