Hi this is not my tank, but a friends tank. 7 gallon tanks with four small gold fish low water level and bio bag is pure black I think her filter is broken. The fish are surfacing and plants are floating around gavel moved, the fish have not bin feed for about a day and aren't moving so much is u could help that would be great I was thinking to kill the fish dump out the water, get new filter wash gravel and plants and cycle it for like 5-7 days with out fish and get one or two gold fish this time and try to get them a automatic feeder, wash the tank and so on. Plz help anything will do.
