Sorry I'm a noob fish owner I do not have any water parameter measurers. (I really should get them)1. The tank is WAY WAY WAY to small. Better pictures will help. Also what are the water parameters?
Seems like there is a singletail in there too- which realistically means 100+ gallons. I was just trying to reason with the OP, because any tank is better than what they are in now.The way that your fish are sitting on the bottom makes me think that they either have ammonia/nitrite/nitrate poisoning or SBD. What does their diet consist of? Goldfish should be fed mostly plant matter and frequent high-fibre foods like blanched, skinned frozen peas.
I'd recommend getting a 75 gallon tank if they are fantail goldfish. I also highly recommended getting a test kit to make sure the water isn't literal poison.
Could be ammonia burn too. I don't think you can sustain them in there even if you change the water twice a day. Rough. That's like a 5 gallon with 5 decent size fish laying on the bottom with clamped fins. I don't need to see test evidence to expect ammonia is an issue.Also the small goldfish has turned silver, do you know any causes for that?
No responses from OP.
Well if this just happened this afternoon, those goldfish might not see sunrise againMaybe went to bed?

Lets hope for the bestI think this has been building day by day. Someone will still be alive. Especially if the OP at least did the water change. I can hope.
