While I have had Bettas before, I am still a bit worried about my new boy. For those that don't know, I got him at Petsmart and before him I had another one (from Petsmart) that died within days. Thus, I am just trying to be sure this boy is healthy.
My question is this
: What is the normal activity level for a healthy Betta fish? Do they swim continually? Or are they more likely to be still at the top of the tank with periods of swimming?
I just want to make sure my boy is acting normally and not lethargic. I've looked him over closely and see no physical signs of illness or parasites. But his activity is a touch worrying, as he seems to spend a lot of time just being still. He could of course still be getting used to his new tank, I have only had him a few days, not even a full week yet.
PS - I should add that I do have a heater, and it keeps the water 78 degrees. So, the fish is not cold.
