Aquarium Advice FINatic
I hav a 2-2.5in koi and he has been swimming really weird lately. It looks like he is missing fins but is growing new ones. Does anybody hav any idea what this might be?

I know you know this but rehoming those fish ASAP will really help out with their health. I don't keep goldfish myself but I'm not even sure if you can keep one in 40g. I may be wrong though.[/QUOTE
Mumma is correct. 8 goldfish in 40gal is 8 too many! Please rehome them as soon as possible. They realistically need a minimum of a @500gal pond. Koi grow to be 36in (3ft) & can live 50yrs. The commons grow to be 12-18in & live over 20yrs. Healthy water may be enough to cure your sick fish over time-if it isnt, treating him will be tricky because you need to move him to a min of a 50gal tank for treatment.
