Hello!!
I have a new tank with a juvenile Oranda and a Ryukin.
I've had the fish for about 3 weeks, and the tank has been running for about 6 weeks and everything has been perfect until a couple of days ago.
I noticed the Oranda looked to be missing scales but they almost look like they're just changing into shiny scales?
I have the tank set at 21.5 degrees because I have plans to introduce a pleco or cat fish eventually and I've been told that they can change colour in heated tanks?
I also had the nitrites in my tank spike around the same time but have since gone after a couple of partial water changes, the nitrate is sitting between 20-40.
It's a 28L tank with only the 2 goldfish in it.
Both fish get along really well and are both very happy, swimming around with big appetites so I'm just a bit confused what could be wrong.
Hope someone can help, thank you!!!
