So for a couple of weeks I was on a hunt to find a new koi betta (I am very obsessed with koi betta), and ideally it would be a female since they are half the price as males and just as beautiful. I went to Petco (They are the only chain pet store that sell koi betta), and they had these baby female koi! They were so cute, and I picked out the female with more growing spots that were red and black. She had more potential. She probably seemed around 2-4 monthes old since she is so tiny and has not fully developed her spots, but already has streaks in her tail. Her fins are short and thin. After floating the water and poured her out into the 5 gallon I have set up for her, she instantly started zooming around and exploring her new tank. I named her Star since all my pets (dogs, cats, other fish) are named after something in space. Star ate like a pig, she was super vibrant and lively. So much sass and spunk. I woke up this morning and saw that Star had built a bubble nest! I know this can happen in female bettas, but not in babies really? And I swear that her coloring is so much more vibrant and colorful then when she was in the cup! Funny thing is that my dad said that, when Star was in the cup, she seemed not very energetic. Currently, since she is the only animal in the tank, just put in some aquarium salt for good measure. Also feeding she bloodworms for most of the time and slowly to high-quality fish pellets. Tried to do research on juvenile bettas and so far not much has come up. I have some questions: -How many bloodworms should I feed per day and how many meals? -Normal for baby female bettas to make bubble nests?
