Fish love blanched veg, with dry pellets try soaking them in pond water so they go soft, this could help just in case they have a bouyancy problem as well.

Well you need to move onto normal food once you've read the garden peas once. The peas are a laxative so the fish are going to get worse if you feed nothing but peas. Now you've cleared them you need to start feeding them up to strength.

It is done if theres poor water quality, but you could ahve poor water quality if somethings got in which normal tests cant test for

Only treatment you could add if you wanted to was salt and possibily a strong anti internal bacterial treatment.

Ill try the blanched veg and pellets. Ill also do the water change this weekend. Any particular type of veg?

Personal id just use normal pellets without blanching them, you need to get as much nutrients and protein into them as possible

I have been feeding the fish normal pellets soaked in pond water for a few days now and i'v also done a 50% water change. How long before i start to see any improvements? p.s thanks for everyones help :)
