Got back in to this hobby about a year ago. Currently only have a 20 gallon tank, which houses 12 fishes, making it a community tank.
Things have been great but have to admit I have lost some due to not knowing what I was doing.
Fast forward and things have calmed down, without any others dying. Nitrate has been a constant battle which has led me to weekly water changes (50%). Also as of late but cutting how much I feed them in basically in half.
What it seems to be happening is that one of my Goldfish who is currently all white (used to be gray) is now turning orange. Is this normal?
I am sure you’ve been told but common goldfish like the ones you have need 75gal or more each
You can’t even keep fancy goldfish in a 20gal without the risk of major issues
I can promise you that 12 fish in a 20 gal tank where some of them are common goldfish will give you trouble. A lot of trouble. If i were you, i’d rehome the goldfish to a pond and look into what can live in a 20 gal tank (that also is tall). Its not much really!
Yes, goldfish are messy as fuck so the water parameters and tank quality will suffer
