Nervous looking tank
Got my 75 gallon started. stuffed it full of fast growing plants, not worried about aquascaping at the moment. My plan was to have smaller sized fish in the tank, started out with Otos, 10 Brass-Gold Tetras, 3 Sparkling Gouramis, 2 Dwarf Loaches from my 30 gallon, and now after my husbands visit to the LFS, he added fish to total 20 brass-gold tetras, 4 dwarf loaches, 6 SAE, 2 Pygmy Catfish (so cute), and now the tank, although still large, looks "busy". The fish don't school, they just swim and dart about, the fish look restless, not the look I wanted at all. Why doesn't my school of Tetras look calm and beautiful? What type of fish can I add, (or take out) that would look better? Would a few larger fish look better than a large school of small ones?
PS The same fish looked gorgeous in my 30 gallon--why?
