I just got 4 male bettas yesterday and I'm a first time betta owner. They're so beautiful and seem to be content. They're small still so probably babies I assume. I bought freeze dried brine shrimp and pellets for them.
How often do I feed them? I've been fish sitting my friends bettas which are adults, and they eat the pellets twice daily. Also, is there anything I can do to keep them happy and entertained? Possibly play music in the room or put something in the bowl?
Side note: I purchased my bettas at Petco, they had a huge variety of colorful bettas there. Although they don't seem well taken care of :(
