Can filter be too strong?
Strong aquarium filter current can damage fish fins. They might put extra pressure to fight off the current and end up damaging their fins. Plus, your fish might get stuck in the decorations because of strong water flow.
Why is my betta hanging out by the filter?
Bettas like to hang around near the outlet of the filter because that spot has a good flow rate. A good flow rate means that spot has more oxygen than the rest of the tank. However, if the betta struggles to swim straight, that means the current is too strong for him and you need to do something immediately.
Why is my betta hiding behind the filter?
If you see your betta hiding away behind the filter intake or under the outtake even though he has plenty of other hiding places at his disposal, it could be that there’s a problem with the water quality in the tank. Fresher water comes out of the filter unit, and that’s probably why your fish is hanging around there.
Do noise filters bother fish?
Several studies on fishes have shown that behaviour and auditory sensitivity are often affected by underwater noise. Noise spectra showed that all aquarium filters measured created a high amount of low-frequency noise, while the water outflow above the surface created additional high-frequency noise components.

Do clownfish like high flow?
Clowns aren’t big fans of high flow but they’ll often just avoid high flow areas in the tank.
Can you over filter a tank?
You can’t really over-filter an aquarium, but it’s fairly easy to under-filter one. Most aquarium filters are rated according to how many gallons the aquarium holds. For best results, purchase a filter that is rated for an aquarium a little larger than the one you own.
How do I know if my filter is too strong?
When the current in your tank is too strong, your betta may look like he’s struggling to swim. It almost looks like he’s getting blown around in the wind. However, if your betta has come from a small cup, then you have to remember that his muscles are probably to weak to swim properly.
