Try adding live plants into the tank or make sure you have a good layer of gravel for bacteria to grow in. Perhaps the tank needs a few weeks to cycle and once it does, the ammonia levels will be kept under control a bit. You will obviously still need to perform water changes but not as often as you are doing now. See: Adjust the nitrogen cycle in your fish tank
Two comment one the fish swimming up side down could be there swim bladder problem and the guy I got my goldfish from told me to use frozen peas just unthaw them and put a few in the tank.
And the other comment about the insect like things on your goldfish also could be fish lice my brother got some goldfish to feed his fish and the feeder goldfish had fish lice he told me it was like little spiders all over your tank and fish how ever my brother did treat the tank but the lice was every where in the tank so it killed his fish.
Hope this help
Hello I have a few questions if anyone can answer me I just got ranchu goldfish however I have had them in the past but they died because I honestly didn’t know what I was doing so here yet again with another one I have had for a few weeks now so far I have had to treat ick and I did have to by a new filter system because the other one went to hell and soooo because of the new filter system the ammonia levels have been crazy I have been doing water changes and putting ammonia tab I got for the pet store I tryed using ammo lock but that seems to not work as well as the ammonia tab I got from the pet store,I really don’t want to lose my fish I paid a lot of money for her ,I did talk to the guy I got her from and he did say it was the filter system I had to get it don’t have the bacteria to break down the ammonia yet so I got some live bacteria supplement the my husband and I came up with taking one of our filter system off our 55 gallon and putting it on the 30gallon I have the ranchu in and I would just put the new on the 55gallon so with all of that the ammonia levels are still crazy and I still have to do water changes of 30% sometimes 50% depending on the ammonia levels,I just can’t figure out the the #### I’m doing wrong I have listened to everyone one on what to do and did reading on line and I’m just all out of answer and its driving me crazy, I really wanted to try with another ranchu goldfish because I love the way they look and there peaceful ways. Anyone have any better ideas because I’m getting tired.sorry if spelling is bad doing this on my phone so it hard to go back and fix any missed spelled word hope everyone can understand.
