Tetra Stocking Ideas

[fishmad135]

Hi!
I've go to a stage were all my fish (other than my cory catfish) have died of old age. As my only fish are at the bottom of the tank theres a lot of space up top for a shoal or two. I love tetras, they're so beautiful! Bearing in mind that I have a 20 Gallon tank with 6 corys and I am strict with my water parameters and weekly changes, what fish (tetras) would you recommend? And how many? 
 

 
Thanks!

dimensions of tank?
 
If suitable tank size, how about Rummy Nose Tetras?

I second the Rummy Nose choice.  Very peaceful and colorful. It is best to have a minimum of 5. 20 gallon is not a good size for giving you much shoaling options, but the frequent water changes help

I don't have a tape measure to hand but off the top of my head I know the length of the tank is 27 Inches, cant remember the width or depth though!
 
Rather partial to Rummy Nose, spoilt for choice!

27 inches is a bit short for rummy nose tetras, they prefer really long tanks as they love to swim around and they really are doing best at 10+ numbers.
 
I know it is really a classic choice, but a large school of Cardinal Tetras is really a stunning view.
Not a Tetra but Harlequin Rasboras are really nice as well and school thighter than cardinals.
They also are very beautiful against a planted background.

I do enjoy my harlequin rasboras.  They school tightly, as l_l_l said above, they stay at the upper level of the tank and are very attractive IMO.

Agreed, under 30 inches is a little short for my original choice of Rummys but that did depend on dimension of tank,  but I_I_I's suggestion of Harlequin or even Galaxy Rasboras (they usually take mid to lower level of tank though) but would be good choice for that tank size.

i'd go with galaxy rasboras and shrimp
