I've had my Ryukin goldfish for a couple months now, I've previously kept fish. She's a medium size. In a 20 gallon tank, alone, with 20gallon filter. Tank temp 69.7 F, ammonia tested yesterday 0, 0 nitrite, 7.6PH, we have hard water here. I don't have a nitrate kit, is the nitrite an indication? Should I get a nitrate kit too?
Petsmart told me to give her Omega-One goldfish small pellets. Later, she got swimbladder and floated completely upside down for a while (for 30 seconds, I thought she died), then it got better. I now know fancy goldies are prone to this. Petsmart guy recommended HBH Super Soft Spirulina that helps their goldies when they get like this. I tried it - it make her WORSE. Even after soaking it, it still is bad. So I am not using that anymore.
I tried the pea tactic and it works wonders, but I am afraid to feed her peas ALL the time, I am sure it's lacking in something they need. Today I tried the Omega-One food presoaked again and so far, no floating.
Is there a premium food out there that prevents swimbladder? Can a fish recover from this? Should I supplement peas daily with the fish food or leafy greens?
And I am very confused. The back of these fish food containers says 'feed 3 times daily, as much as can be consumed in 2 minutes'. I think that leads a novice to overfeeding. I feed twice a day and am giving her 6 pellets per meal + peas. Is that okay? After the 6 pellets she won't eat anymore and it's waste on the bottom of the tank.
Should I give her some freeze-dried bloodworms as a treat? Or no..?
I do a water change every 2-3 weeks and replace the filter every month and a half. Is this good?
Thanks in advance.
