I'm off to get some new additions today as our water is finally settled... but having second thoughts. the original plan was for 8-10 diamond tetra and 6 or so cherry barbs... now we already have 5 black neons, 3 dwarf gourami, 3 lyretails and 6 parrot platy... im just wondering if that would look a bit naff with no sorta 'centrepiece fish'... any thoughts or suggestions? what about rainbow fish?
