Hi guys! I am very sad because my 4 year old betta is starting to slow down and spends all his time resting at the bottom of the tank.(water parameters are good, heās been slowing down for a while now) In order to breathe, he has to rush to the top and then goes immediately back down. I feel bad for him having to travel so far, so I want to lower the water level so he is more comfortable. However I cannot lower the water level with my filter that hangs off the back. Would it be ok if I turn off the filter during his last days so he is more comfortable? I could do more frequent water changes if necessary. (It is a 10 gallon planted tank no tank mates)
