Hi all,

Need your advice... I have been rearing goldfish for more than a year now but non of them have survived more than 5 -6 months. 10 of 10 died of dropsy. I don't understand why they all develop this disease eventually. Usually one at a time. Can someone enlighten me ?

I have like usually keep about 5-6 gold fishes (2" - 3") ranchu/lionhead in a 2.5' tank (100liters).

Change 1/3 water about once a week. Adds about 2 tablespoon of salt per 20l of water at every change.

I feed them mixture of pellets (hikari saki/lionhead/wheatgerm). My goldfish also prone to floating. After feeding .. even sinking pellets, will float.

Non seem to have survived once they get the disease.... Please advise if you have any possible solutions...

Cheers
