Previously I posted that my male and female betta (dual tank) have both been sluggish but especially my male. You all suggested that I get a heater which I'm planning to do.
I'm watching my male this morning and when he does swim to the top of the tank (feeding time) he is like dragging his hind end
. And then once he eats he goes back down to the bottom and starts sleeping again.
Why is he dragging his hind?
Also there is like this stuff around him (not gold looking like velvet), kinda looks like he is shedding. Do bettas shed?
