Here recently my goldfish past away
So, I took a break from keeping goldfish, but I just now wanted to get back into keeping them so I went online to my favorite place to order good quality goldfish (River Garden Nursery). I ended up ordering a ryukin from them and will be shipped to me Monday morning and I have had this 20 gallon long aquarium set up with a sun set 600 filter and was wondering if that would be suitable for a quarantine tank for a few months so I can collect money to buy a bigger one? Please help me out I want to do right with this new little guy I'm getting.. (By the way the goldfish is pretty young and is only 4 inches from head the the start of the tail.)
