I've noticed every time I change my betta's water, Tifa and Nina get the same "stress bars" they had when I first picked them up at Wallyworld. I have to do this often, as I do not have the room for a filter or anything like that.
Winston's pretty used to it by now it seems, but he by no means likes it.
I normally either net them and put them in a cup temporarily, or use the cup itself to catch them, since I really have nothing else, and can't think up any other way to do it.
It makes me feel so bad, but I mean.. it has to be done.
Any tips from the pros about how to get them out of the tank without scaring the poop out of them?
