I have a pond about 800L and about 40 gold fish in it
2 days ago i saw 1 dead fish floating It had white bubble/lump types of things on its side and near its eye.
Today when my dad was going to clean the filter once he lifted it out of the pond he found a dead fish stuck to it. it also had the white lumps on it.
i had a look in the pond and counted atleast 8 fish with the lumps on them aswell.
i will try to get some photos tomorrow.
Please help me i dont know what to do.
