It's a 30 litre tank - about 15 inches across & the depth is 8 1/2 inches. =/
I think we've got quite hard water, we use a water softener for most of the taps in the house but that's no good since that makes the water slightly saline. (which I think does more harm than good - my hair is an absolute nightmare. xD)
^-^ Ember tetras look good. And the cories. I'll have to see if I can find them though~
Find out your tap water parameters first. If it is very hard and basic, soft water fish like Ember Tetra and the dwarf cory species will not do well. And when I say tap water, I mean the water you use as source water for your aquarium, which from what you say is not via the softener. And I agree, depending upon your softener, they can cause more harm. This is a general statement, one needs to know all the specifics to be certain.
If your source water is tap water (pre-softener) and from the water people (not well water), you can probably find out the hardness and pH from them. Many have web sites with this info, or they will tell you. As for the GH (general hardness) and KH (carbonate hardness) and the pH. They may or may not have the GH and KH separated, but if they do get both.
It is absolutely essential to know the water parameters of your source water before any fish can be decided; some adapt, many that have specific requirement do not. This is one of the first things all aquarists should know, but many never think of it.
