I need some advice. My new betta is in a 2.5 gallon tank which came with a small filter. I also have 3 guppies in the tank.
My question is this: Do the Bettas need flowing water? I know they naturally live in still water. I have turned the filter down to it's lowest power but because the tank is quite small i still think it is a little strong. He isnt fighting against a current but of course if he swims past it then it will.
I dont let it run 24/7. I turn it off at times, especially when he eats and also at night so that he can sleep but im not sure if I should have it on at all. of course i know it's good for filtration purposes but i dont want it causing him any stress. And i feel like the guppies are 100% with it.
If the tank was double the size the flow would be substantially softer but for right now i dont have the space for a bigger aquarium.
