I currently have a goldfish in a 10 gallon aquarium, and he's been doing fine for the last six+ months. Several times in the past couple of weeks, however, I've found him sitting on the gravel. I do a weekly water change of about 30% and am buying a water test kit today so I know what the water parameters are. I know the ph is in the 7.0-7.2 range though. I read online that sometimes filters can be too strong for the fish, causing them to sit on the gravel—little Winston definitely struggles when he gets near the filter. I can see him pushing to try and swim past it, it's actually quite pitiful. Does anybody have any suggestions?
I have the Top Fin 10 gallon aquarium with the filter that came with it (the Whisper 10i).
