I have worked my tank out at 6-7g, is that right for 29L?

Thanks for the recommendations - are all these fish suited to aquarium sand because I have ordered some? What would be the best combination if it was you choosing and also what amount of each would be suitable? DEFINATELY like the Pentazona's. Maybe a combination of 1 Betta, some Pentazona's and a few Neon's....would the Betta eat the little men?

My equipment has been shipped so hopefully I can get set up by weekend.

I am off to the aquatic centre tonight for a good old nosy!
