when i woke up this morning, i found Jake lying under the plant decors. he was cold dead. i really don't know ehat happened, but i have some ideas. you see, he is in a 10gal tank divided into 2. the other half has my mollies. last night, i gave him the usual food that he eats and he frantically reached for it as soon as i dropped it. after an hour, i made him do his 2min flaring as an exercise and he still did well. after that he continued working on his bubble nest like he always used to. before i went to sleep at 11 PM, i treated the water with a water clarifier because the water is too cloudy.
i have 3 suspicions why Jake died:
1. The mollies killed him.
i saw him in the space for the mollies. he jumped from his space to the next one. is it possible for mollies to kill a mature betta? are there instances where a group of mollies attacked and killed a betta? i have 7 mollies altogether.
2. He was poisoned with the water clarifier.
Can this be true? the bottle label doesn't have the ingredients of the solution so i can't tell if it has toxic substances in it. but the label says it is "safe for all aquarium inhabitants".
3. He died of old age.
Yesterday, my gf and I went to a pet store to scout for a new betta. we noticed that most of the bettas are a lot smaller than my Jake. Jake has been with me for nearly a month. is it possible that we picked up the oldest fish in the shop that wasn't sold for months?
My gf and I was really sad this morning. We have to go to work feeling like this. I hope my next betta will have a longer life with us. I'll make sure that everything is in good condition before i purchase a new one.
Thanks to you all!
