How much Oxygen is too much? And stocking Q...

Hi Everyone! I am in the process of upgrading from a 5 gal that I've had for 3 years, to a 10 gal. In my 5 gal I have a Rosy Barb (3 yrs), an apple snail (3 yrs), and a pleco (about 3 inches - only had him for a few weeks). All of these guys will be moving into the 10 gal as soon as I'm done with the fishless cycle (almost done cycling - should be ready within the next 3-5 days). I would like to get some more Rosy Barbs to keep my current Rosy company. I'd also like to see some other types of Barbs in there. I wanted to get 3 or 4 more Rosy Barbs and 2 of another Barb such as a Tinfoil. Is this too much for a 10 gal? Also, my 10 gal is set up with a bubble wall 1/2 the length of the tank and a decorative bubbling treasure chest. I also have a HOB bio wheel. All of these are causing quite a lot of turbulance in the water. I know that it's good to have a lot of oxygen in the tank, but is there such a thing as too much? Would all the turbulant waters bother the fish? I read on another thread that you can put slits in the tubing to reduce the air pressure. Anyone else try this or have other suggestions to lower the air force without having to go out and purchase a new air pump? I even tried stuffing a bit of cotton into the tubing to diffuse the air, but it really didn't make a difference. I got this pump because it had 2 outputs, which I liked. I tried using a smaller pump with a T in the lines to bring air to the bubble wall and the treasure chest, but there wasn't enough force to make them both bubble. Any suggestions?
 
You would have to have a pretty major air pump for bubbles to disturb the surface of the water too much, so I guess I wouldn't worry about that too much (unless you do have a really major air pump for some reason). As for the Bio-Wheel, I keep my water level right up to the bottom of the outlet (I don't like the splash noise), and that seems to keep the effect on the surface of the water down as well. Most of the oxygen gets into the water when it tumbled down the little slope and hits the wheel in that kind of filter, so don't worry about reducing your oxygen levels that way.
 
Hello, You can go to most LFS and purchase a small guage that will allow you to turn down the amount of air coming out of the the bubble rock, not the air pump. It hooks inbetween the tubing and hangs on the tank. If you don't hae plants in the tank then you will have no problems with to much oxygen.

I myself am rather new to the hobby but the pleco you have can grow to be pretty good size. I have heard that you will need at least a 55g for plecos. They tend to grow about 1/2 inch a month if taken care of and some can grow up to larger then 12 inches.

Tinfoil Barbs will need a larger tank then a 10g as they mwill get aggresive twords the other fish as they won't have enough space to swim around. If it were me I would mabye get 3 more rosy barbs and say 4 Gold barbs. They should get along pretty good. I would think about a bigger tank for the pleco or giving it back to the LFS.

If I am wrong about any of the above someone please correct me.
 
Tinfoil barbs, like all barbs, are schooling fish and need to be in groups of 6 or more. They also grow to 14", so nothing short of a 75g will do for those guys ;)

Common plecos can get 12-24" and the min tank for those is a 75g for the "smaller" ones.

Please consider upping your rosy's school to at least six. She's been alone for a *long* time and she could use a real family.

My Rosy has only actually been alone for a few weeks. I had one other in there for the past 3 years. As soon as he passed away, my Rosy that is left has been super hyper. I am really looking forward to getting him some other Rosy's to school with! I am eager for this tank to be ready so I can bring him some friends!
 
Hello again, another idea for you if you could get a few more rosey barbs and get some Harlequin Rasboras. The Rasboras are more of a top side fish so they will usally remain in the top to middle of the tank were the rosey will remain twords the middle and bottom. Also the Rasboras only grow to about an inch so they won't overcrowd the tank. I have 6 and love mine, they seem to get along well with the other fish that are in my tank. Just another idea for ya.
 
Get yourself at least 6 more Rosy Barbs. I would reccommend 7 as a bare minimum for these fish. They are very active swimmers and also very greedy at meal time if you have not already noticed.
