These are very small schooling fish that stay near the top of the tank, they eat flake food or anything else that will float and will occasionally dive to the bottom to check out sinking foods. I have 10 and plan to add more, they are about 3/4 of an inch long with a blue stripe that runs from nose to tail and reflects beautifully whens the lights are on. These are most likely the smallest fish you'll ever keep but remember to buy a large group to keep them happy Update: Now that these guys are feeling at home they don't really school at all anymore, they tend to break into small groups and wander about the tank from high to low and seem to love swimming into the current of the filter exhaust.
got 25 of these. mine actually stay near the bottom of my 56G column (24" tall) tank. I wish they would spend more time higher up. been thinking about getting more of these, but may get something else to add orange/red colors to my tank. o
The shade of blue on these fish when the lights are on is just beautiful. Good slow acclimation is important. A well-planted tank is helpful too, as these fish tend to be skittish if there is too little cover. Although they may be a bit sensitive at first, once acclimated they are relatively hardy. Mine like to travel all over the tank, and will take foods from all levels of the water column.
I got 14 of these for my 36 gallon a few weeks ago and I'll be getting more shortly. I acclimated them over a couple hours and got them from someone who kept them in water with a pH over 7, so I think that helped. My pH is around 7.4. I didn't lose any fish out of the shipment I received. I love these guys. I thought they were going to be shy but they're actually the most outgoing fish in my tank. My tank is very heavily planted but they never hide in the plants. If I stand next to the tank they start swimming toward me. I was trimming something in the tank and they were following the tool I was using. They do tend to stay in the very middle of the tank, in the top of the lower half. They eat like rowdy little pigs and are getting really plump. They get flake, frozen, sinking wafers, they'll eat just about anything you throw in the tank, from any area of the tank, and after feeding go right back to their spot in the middle among the plants. The color of their blue stripe is incredibly electric in dim lighting, varying from blue to green to purple depending on the angle of the fish. They do have a short patch of red on them like regular neons but it's not as prominent.
I think I have standard Neon Tetras. My school inhabits the entire column. Some individuals eat mostly from the top, others the bottom. I've had my school as long as my tank 9 months; in fact I broke my tank in with these fish, and didn't lose 1. Neon Tetras can be hardy, but I also treat them like a miners canary, as suppossively they are sensitive to bad water conditions. The fish remind me of brightly colored trout, and part of me wishes they got 14 inches long and I could fish for them. They have sleek bodies and a tail meant for speed. They are a fun fish to watch and eat just about everything. Like some other fishes, you may have to get these puppies settled in before their true colors start to show. I have not had a problem with these fish yet.... Most of my fish are about an 1" and a little bit bigger...
Beautiful fish. I have 14 and although they primarily school when the current is lower, they have in my opinion the most pronounced blue line compared to neon and cardinal tetras. Excellent for adding color to a heavily planted tank.
Not as active as cardinals, neons or rummynose but still very active. Mine were shy and mellow at first but after adding a powerhead they went nuts and became active. Not sure if flow has anything to do with the change in behavior but to me they seem happier with the extra flow so I assume they like to have a bit of flow.
Even though these are small fish, a nano tank wont really let them school together very well. 10 gal or more is the usual recommendation. I have 10 green neons in a 12 Gallon long planted tank with a small powerhead to provide current. One of the coolest things I have noticed is at night their coloring changes. When I turn on the room lights while its still dark outside, but not the tank lights, the green neons have a glowing aqua blue hue spread over their body instead of just the shiny stripe you see during the day. I was so surprised to see this awesome glow. But After the lights are on a while the glow disappears and the normal neon stripe returns. Has anyone else noticed this?
