I had no idea the goldfish was dead already... sorry I guess I missed that part.Thanks for the info buddy but you do sound like a 'broken record'. Yes, I know the goldfish was in a smaller than usual aquarium and he/she might have died due to ammonia poisoning and I've said I'm sad so what's the use of beating a 'dead horse'?
Also, as I've said that I've revamped the aquarium and checked for most common issues and found none so far. Also, the Danios died 5 days after my goldfish died. Since my Oranda died I've done two 20% water changes and did Ph, Ammonia and Nitrate before introducing new fishes.
It's only upon introducing my new 5 Platies, 4 Corydoras and administering Melafix and Pimafix did my Danios die. Also, I've done another test yesterday for Ammonia and Nitrate, where Ammonia is Zero and Nitrate at 5ppm so I'm due a water change today.
Not to be mean to you, but please read the thread....
I was just trying to prevent it possibly getting stunted.
I do appologize for your loss and if I offended you in any way
wish you the best of luck
