I'm goin crazy trying to find out if this is just a normal thing fish do and im just worrying for nothing.
So basically is it normal for fish to just kinda...twist/snake around sometimes? It's never panicky or fast or continuous but sometimes I just catch him doing this. hes just swimming, he stops does a slow/stationary like S snake-like motion or a kinda 8-like twisty turn/flip then just goes on about his day. It's hard to explain! Is that normal?
Eating normal, no fast breathing, no other symptoms. Is this something to worry about or just a normal fish thing?
