These are my first bettas so ignore the ignorance. I got two male bettas yesterday along with everything that was recommend to me by the petsmart guy. I got a huge tank and it has a divider for them so they don't attack each other and I set up the tank yesterday with the filter and purifier or whatever it's called and waited 24 hours before putting my fishes in there following each and every instruction. Yesterday, the white betta was fine and ate well while the blue betta would not eat at all but was very active. Today, I noticed the white betta was not active at all and for a second I thought it died until it started to slowly move again but wouldn't eat either. Once I put both of the bettas in the tank, they both are not eating still and keep staying on surface while occasionally moving in the middle of the tank. The white one would occasionally go hide as well. Is that normal? They were quite active at the pet store, that's why I picked them.
