Thank you Lyra I've been scowing the whole country for decent well priced goldfish and managed to find a place actually not too far from me in Surrey.
It seems noone wants to keep goldfishes anymore and its about tropics these days.
I have done a video of the whole tank its not finished yet I have some slow growing plants that will take time to spread before adding to the tank.
I don't think my Ehiem 2217 can handle the bio load so waiting for it to stabalize longer before adding anything else in there its 300 litres and wanting to go bigger! LOL
