what are some small fish that swims in the middle(dont want bottomfeeders) of the water? guppies?

I might as well not have gotten the fish i did - 6x zebra danio 6x whiteclouds ALL hug together at the surface of the water. With my biorb's water pump making the water surface constantly moving, cant even see them. The entire tank looks completely empty. So i am thinking of adding a fish that swims in the middle of the tank.

any ideas? thanks.
 
Tetras

Most of my Tetras and my Danios swim all over the place, I am wondering if there is another reason yours are hanging out on top like maybe they can get more oxygen up there. You might want to check your ammonia levels.
 
If that is an 8 gallon tank, I'd remove all the danios ASAP. If all danios and whitclouds hang at the top, there may be a lack of oxygen or there may still have some chlorine in the tank (use a tap conditioner).

Even if it's not an 8 gallon tank, I'm guessing it's still a small tank and I'd remove the danios, they simply need more space to move around because they are quite active!
 
ok it's a brand new tank, i just got the fishes today. They stayed in the ups box for 2 days while getting shipped to me.

I spent 1 hr doing the usual acclimation process and then released the fishes into the tank/bowl 5 hrs ago. For the past 5 hrs, they NEVER went to any part of the tank but the top. Should i be concerned?

Here's what i did:

1) setup biorb
2) add tap water
3) add bio-safe (remove chlorine)
4) turn on biorb
5) run test with master kit, everything at 0, ph 7.0 exact
6) left it running for 24 hrs until tonight
7) acclimation for 1 hr
8) test water, same result - 0 everything, ph 7.0 exact
9) add half pack of bio spira
10) add fishes to biorb
11) 5 hrs later...
12) run water test, 0 everything still, ph 7.0 exact...
13) all the fish continue to remain on top of the water...

I havent fed them yet, dont plan to do it until tomorrow morning. But now im concerned, you said i dont have enough oxygen? :(

most people assume the biorb doesnt have enough surface area, that's completely false. If you follow the instruction and only fill the water to 2" above the pump, you have a HUGE surface area. It's only when you try to fill up the entire bowl then you have issues.
 
well i thought maybe they stayed on top because of hunger, so decided to feed them a little bit of bio blend but didnt know it had two #Y@(#@ different openings on the bottle cap, ended up pouring half a bottle into the tank.

this is turning into 1 giant disaster, i am getting the food out by hand right now with a tissue, didnt buy a water vaccuum yet. arggg
 
guppies like to hang out at the top. I have some harlequin rasboras and they swim in the middle.
