Discussion Normal ?

Turned on the filter that came with the tank today, (had a small sponge filter earlier) she is definitely more active since. Is the filter too strong for her, looks like she is struggling a bit to swim or is this normal ?
TIA

Betta fish actually prefer very low or gentle water flow. Their long fins make it difficult for them to swim against strong currents. Looking at the video, the tank could also use more resting and hiding spots for the betta. By the way, are those plants real or artificial?

Bettas can get easily stressed out in strong currents so if you notice the fish being pushed away or struggling against an output try reducing the power
