no my goldfish havent taken to wearing trench coats and flashing went i past their tanks.

i think its called flashing. one of my fish rubs against the gravel he only does ever now and then another fish does it every now and then too the other two goldfish dont do it at all. there is no marks or skin changes and have tested the water everyday for the past week and cant find anything wrong there. im i being paranoia and they are just having a scratch or could their be a problem

any help be great

tums and silveeo mum

could be looking for food .....

or have an itch , if you are still worried just give him/her a salt bath! or put some salt (only use tonic salt) in the tank

thanks for the reply kim

think i fix problem by accident, one of my goldfish got a small scratch i added melafix to help the healing of the scratch then notice the others arent scratching either. Im told i get paranoia about my fish and worried to much about them.
