    The neon tetras dont grow very large, it is possible the the other fish you saw were cardinal tetras which grow a bit bigger. You can tell the difference by looking at the color. The cardinal tetras have a red stripe all the way down there bodys. The neons dont. Hope this helps. :-D

    Hey I have some neons and 2 of them are almost 2 inches which is goliath for these minis. They are the same size as my black neon tetras. Common neon average is an inch but if you have a dozen or so don't be surprised if you get a couple 2 inchers (probably females) or just strong genetics like humans, we have our Shaquille O'neals and we have our Willows. If you want tiny fish that stay tiny go for cardinal neon tetras, which are the size of feeder guppies or their smaller cousin which are fairly hard to find, the wildgreen neon tetra which are the smallest I've ever seen, adult size a little larger than molly fry.

My tank consists of 3 black neon tetras, 9 common neon tetras, 1 painted glass tetra, 3 fruit salad tetras, 3 beautiful clown loaches,a striped raphael,and a leopard sailfin plecostomus.I have had my tank for about a year now and they are all growing and healthy. My water is slightly soft and slightly acidic, which is ideal breeding water for alot of fish, including neon tetras. 6 of them have what look like gonopodiums so I think they are males and my other three are much larger and plump. Occasionally, the bigger ones become very very dark in color and I have heard of pregnancy spots on fish but this is a full black coloring over the whole body .Are they laying eggs? any hints or suggestions?please

    What filtration?

    Get a couple more silver dollars. They don't like being by themselves.

I have a 29 Gal. tank with neone/black phantom tetras, along with corydora cats and a pleco. Periodically my tetras develop a bloated look, distended abdoman etc. I cannot figure out why. They are in water p/h of 7-6.6 78 degrees, water is well water with a conditioner attached that produces mineral free water. I cannot understand why they develop this condition. Can you help me.

    There might be ammonia in the water.

Neon Tetras are very enjoyable fish. I've had a school of 6 of these for 2 weeks now. They don't mind my Espe's Rasboras. They swim in and out of the plants and keep themselves to the middle of the water column.

They are very cute, playful and peaceful. I'd recommend these to anyone looking for something small to brighten up a planted aquarium.

I added 10 of these fish into my 165 litre tank, and they settled in right away! These fish seem to really like planted tanks and having wood in the tank really helps because of the tea colour it creates. They should be kept in large shoals and in a peaceful tank with other small south american species. Although discus fish and angelfish should be avoided. These are very entertaining to watch and I will definitely be getting 5-10 more of these fish to add to my tank!

I have 3 neon tetras in a baby BioOrb. I found that it is necessary to change 20-30% of their water once a week. I use distilled water because I found tap water to be too harsh even with the water conditioner treatment. I feed them flaked food about 3 times a day except on the weekends when they don't receive any food. I've had them for almost 7 months and they appear fine. I learned to keep the room temperature a little warmer than I like it (about 69), otherwise they become sluggish and won't eat. I bought bloodworms (freeze dried) to see if they might want a little variety in their diet. I've only seen the snails eat the bloodworms. 2 usually go behind the large rock and 1 stays in front to watch me. The one usually just stares at me with the 2 blue eyes at around feeding time telling me it's time. I don't use the light that came with the BioOrb because Neons like it dark and spooky.

I have 5 neon tetras at the moment but am thinking of getting some more. Neon tetras have become my number one favourite fish species since my plec (Geogre - RIP) sadly departed this world for fish heaven. So I say, neon tetras rule ok!

I love these fish, I got them 2/1/2009, and I am excited to have them. You can almost see right through them. I have three betta fish named Swimmer, fins, and betta, with three neon tetra. They always stay in a school. They are pretty when swimming, but when they are at the bottom of the tank you can barely see them.

A very fun fish! They look really good in bigger schools and should be kept in groups of atleast 5. I found that they're fairly sensitive at first though, and lost several to the filter intake too:( Once settled in they make a great addition to your tank!
