I toss out plants almost every week from my Asian tanks where I have this floating, and the original plant I bought some 12 years ago and have had plants ever since.
Byron. | Thanks a lot for your help. I will probably get the Water Sprite. My tank is ready with a PH of around 6.5, so it's time to get the black neon tetras. Tomorrow is the day. Just a quick final question are Black Neon Tetras the kind of tetras that like an odd number group.

I'm asking about if black neons or lemons are kind of fish that like an odd number like 7. I read that some tetras like odd number groups.

The fish don't care if the number is even or odd, their only issue would be the more the merrier.
Some fish are better in a certain ratio for reasons of behaviour particularly during spawning. In some species the males drive the females hard, and if there are more males than females this can exhaust the females to the point that they become ill and die. In these cases, 1 male to 2 females, or 2 males to 3-4 females, etc. works better, but the end number being odd or even makes no difference.
For many of the tetra telling male and female is difficult until the fish are mature and the females are noticeably rounder. A group of 6 or more will usually contain a mix. I usually get odd numbered groups, but for no other reason than personal preference. In a vase, 3 flowers are better than 2, and 5 than 4, etc. But this is my psychological quirk. 
Byron.

I just made a wonderful addition to my tank. 7 Pristella Tetras. Sadly, the Black Neons were sick and the Lemon Tetras weren't at the LFS.  But, never fear the pristellas were available and next on my list. I also got a Water Sprite and now it's floating around in the tank.  I'll try to post a picture of the fish soon.

Of course, if it's a torrent it may be too much, fish have to work harder the more current they are in, since they can't "stand still" in moving water. But I suspect it is just their getting used to the new environment; most shoaling fish will remain in a close group together when introduced to a different tank, and remaining among the plants indicates they feel more secure there.

What is a good top dwelling fish with the parameters of tetras. No hatchetfish though. | Assuming it is just initial reaction, the Pristella will not remain near the substratel they tend to swim mid-water. The green cory could be Corydoras aeneus, or it may be Brochis splendens. They look "identical" at first glance but the Brochis is larger and higher and has a dorsal that extends further along the back. Check the profiles for photos and other info. Pygmy corys are somewhat sensitive to water parameters and conditions, and I strongly advise only acquiring them after the tank is established (not just cycled, but established, say 2 months).
Top fish are not abundant. I have Nannostomus beckfordi, the most commonly-seen pencilfish, in my 115g and they tend to spend most of their time in the upper half of the tank. They must have plants as they spend the day picking over plant leaves for bits of food. The display of the males is fascinating. Check out the profile for photos, and note the info on behaviour. Although a pencilfish, these guys can be a bit feisty.

And if they don't have enough lemons or the lemons aren't healthy. I have a backup plan. I'll get either Flame, Pristella, Silvertip, or Penguin Tetras.
