A 1mtr tank cant hold any of those fish long term , you need at least a 6x2x2 for the jardini and silvers get bigger , the stock you've got there your going to need a pond very soon , if I was you I'd get rid of most of that stock and do a bit more research into what fish can be housed in 3ft tanks , unless you plan on building a very big pond in next few weeks![]()
