So I woke up this morning to find that the betta I got a week ago died. I'm wondering what could have gone wrong in this process so I don't do it again.
I didn't even get to name him yet :(
I bought him from a local pet store where he appeared in great condition (0.5 gallon bowl).
I kept him there for a few days until I moved for college. He had regular feeding.
I moved him to a very small betta bowl with a cap so I could carry him. Water was from the tap, kept at room temp over night, drops of API Stress Coat was added.
Transport went well. I had brought over a 2 gallon tank with filter, gravel, small fake and small live plant (that came with him). I cleaned out the tank and gravel, set up the filter and such, filled it with water from the school and let it cycle over night. The fish was swimming around in the transport bowl fine.
The next day, I added stress coat to the new tank, and moved him in. Temps were 80-82 in the tank. He went stiff. He sank to the bottom of the tank, though alive, and began heavy breathing. His fins were stiff and curled. He even let himself get sucked by the filter.
I read here that I could leave the filter in and let him gain strength, but I was unsure of this and took out the filter completely just in case. Fish would not eat food.
The next day, I decided to do a 50% water change in case. Here, he was swimming around much more but still fin stiff and was forming a white patch on his tail. I assumed immediately it was fin rot as there was no other indication of other diseases. So I did a 50% water change, added more water from the tap, and used stress coat before adding it to the tank. Fish did not eat food.
The next day, I went to walmart, bought aquarium salt and "bowl buddies water conditioner". The fish was in bad shape. I moved him into the transport bowl and added the salt. He was in there for about an hour while I cleaned out the tank completely. I found some weird green thing that might've been a bug or plant residue.
I added water, about a tablespoon full of salt, and dropped in the water conditioner to fizz out. Once the temp read 84 degrees, I moved him in. He didn't move at all and thought it was due to stress. So I hoped for the best and found him this morning floating.
Sorry for the long post but I'd like to know if I did something wrong in the process, maybe I moved him in and out too much, too much stress coat, improper water changes or bad water all together. I tried everything I could with the time I had, but I can't help but feel like a bad parent :(
