So i just got a Male Betta and an aquarium starter kit; 5 gallon tank, filter, heater, rocks. Im just curious as to what little trinkets and toys and what not the fish like. Im wondering on how to tell if its a male or female, and if it is a male, will getting a female be ok? Or will they just fight? I just wanna get a buddy for him so he wont be lonely. If you have any tips, tricks, hints, whatever will help, its greatly appreciated. Thank you!!
