I have a 30 litre tank which I set up yesterday. (& yes I do know about the nitrogen cycle).
Some people say a tank slightly larger than mind is suitable for virtually nothing, when others say you can have 16 (small) fish in the tank or more?
So I guess I'd like to know what limitations these people are disagreeing on & what fish you'd recommend for my tank?
Also while I'm here I was wondering whether you'd recommend dwarf hairgrass for my tank?
It's currently got a heater & filter going. Here's a picture: (the heater has since been added)
