Hi all, Thank god I've found u 
I rescued a fairground goldfish left swinging in his sandwich bag on a fence and am now I month further, 2 replacement goldfish (don't tell my son) and a baby butterfly loach in a 70l tank!!
I need help as my little goldfish is sitting on the bottom with black/dark patches on his tummy, positive it is water quality as went on holiday for a week an cater totally overfed
I've moved them all into a smaller tank and need to do fish in cycle I think after much reading. Currently the big tank still has the old water, gravel and filter in but where do I go from here??
Thank you xx
