Fantastic looking tank , something very similiar to how i would like my tank to look once it is cycled.
I see you have a school of 10 Cardinal tetra, my favourite fish which will be going into my new tank, but a quick question if you will...do they all tend to shoal together, or do they tend to split up into smaller shoals?
hes a true beauty, i think your cardinals would shoal if you had a few more, as Simonas said i have always found them to shoal, but have never had less than 15
