Hi, It's Diva the female crowntail again! Mommy is thinking about going to petco, and buying me a 5-gallon tank and possibly a tank mate. I'm very hyper, and like to pretend I'm a shark when I eat my food (especially bloodworms). I don't like decorative plants, but love open water so the big tank should be good for me. the thing is, though, that Mommy read somewhere that crowntails don't like other bettas and can be verry aggressive. is it safe to get me a tankmate? And if so, which kind? Mommy wants to get me a red female tankmate.
