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

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.

I just recently bought 3 neon tetras for my 1 gallon fish tank. One of them has died and the others don't seem to be very active. Would it be best to buy a couple more from the same place to keep them company where there is only 2 now? How do I know if they're sick?

    Oh my! You need at least a 10 gallon...nothing less! And you need to have a thermometer to read the temp, a heater, filter system - go to walmart and you can buy a 10 gallon kit. Also, join fishchannel.com - really great advice and guidance. It's free. And you can earn points to get free things - like just simply voting for a friends profile there. Also, mainly number one, you should register at the tetra website - they will send you regular emails telling you what to do and when. I've only been keeping fish for 8 weeks and so far none of my fish have died. And they have a number you can call if you ever want to for advice, etc. But, most importantly, you really have to be dedicated to your fish. Its not just putting them in a tank and hope they live. There's weekly water changes, vacuuming gravels weekly, 6 different tests at least 3x a week...please think about all this seriously before you decide to pursue any further. Good luck!

    A general rule to remember is one useable gallon to every full grown fish.....neon tetras get to be 1-1/2 inches so each fish will need approx. one and a half gallons
  • Kaleigh - 2011-12-24
    8 weeks?!?! omg you have a LOOONNNNGGG way to go......I've been doing the whole aquarium thing for over 15 years and technically a single neon tetra would be okay (not great) in a one gallon tank if it was literally the only thing in there.....I use a one gallon tank for quarantine

    In a glass bowl?? Really, you need at least a 10 gallon tank...imagine...It's like you trying to live in a really small bathroom for the rest of your life...Please get a bigger living area for them...
  • Kaleigh - 2011-12-24
    They're fish. In about 3 minutes they'll forget they are even in a bowl.....neon tetras look amazing even in a glass bowl

I have 7 neon tetra & an apple snail in a tank. They were all trasferred to their new tank due to My betta splenden nibbling the feelers off the snail and the neon tetra really hacking into my betta splendens beautiful fins. My snail had grown back half of his feelers before putting in with the neon tetra and over night his feelers are gone and so are his eyes. I was told neon tetra were placid & lowest of the food chain & would go well with the apple snail. What comments do you have . It may not have been my betta splenden that ate the feelers initilally. They are being fed plenty but only eat from what falls in the water. Not what is on top as I was told they would feed.

hi,

i have 2 pairs of monos and a pair of bala shark, they are all quite small in size. i was wondering if i could add a school of neons and glow lights along with them (I have a 55 gallon tank)

    General rule is 1 gallon of usable water for each inch oyour fish are going to be as adults. You have a 55 gallon and so first you sutract at least 5 - 7 gallons for gravel, decorations, plants, filter etc. So you have about 45 gallons. The monos and the bala will take that many gallons. The second problem is the Bala is going to go to about 12 inches and will naturally assume many smaller fish are food. It is said they are more agressive when just one in the tank, also.

    Your tank is too small for the fish you already have so I wouldn't add additional fish. General rule of thumb is one usable gallon for each inch your fish will be as an adult. Your neon tetras are going to be 1 1/2 inches as adults so for 6 fish - that is nine gallons that you need. You have a 15 gallong but you have to subtract gallons because you have gravel, decorations, plants etc in the tank so maybe you have 12 usable gallons at the most.
    If you have too many fish in a tank - as you do, the fish become agressive, they can become stunted and die. So good news is you need a larger tank for the fish you have. More good news - it will probably be quite attractive with the fish you have.

I recently started my 30 gallon tank, and added about 8 neon's. So far 4 of them have died, but every time I check on them and the water everything checks out ok. Can someone tell me why they are diying on me?

    Testing for what? Pardon my asking, but that means different things to different people. Check the nitrate/nitrite levels, as they can be poisoned by them. Also, I use a mortar and pestle to grind the food into almost powder, literally. That way they can eat easily, as otherwise they will have to spit it out as it's too big to swallow. I feed them 4 times a day, with a current in the tank. I put in my cichlid fry from the nurse net in the 130 gal. into the 50 gal. with the tetras. They school with the neons, and feed with them. When the cichlids get too big, then they get moved back out.

    Depending on how long ago you started your tank, it could still be cycling. Or were ever you are getting fish got there supply of tetras from a bad source.

Just a little addition to the info already provided. I have a 40 gal tank that was already set up and wanted to add some schooling fish, particularly neons. I have three tiger barbs that I don't consider big, or even medium. As soon as I put my six new neons into the tank, the barbs went crazy trying to eat them, and two became dinner. I did manage to get the barbs out and relocated to a smaller tank before they ate the remainder of the neons.
