I have a 9 month old giant plakat female betta with holes in her fins, and then a day later red streaks in her bottom fins and on the two little front fins. She also has a bloody spot near her eye. I think it could be fin rot that progressed to septecimia. I didnt have a heater for her until last week but the room she's in is usually 75 degrees. We had a power outage last month for 3 days during the hurricane and all my betta's water temperatures went down to 70 degrees, then a few weeks later I noticed holes in her tail and then the streaks. I started her on API tetracycline according to the directions on the box & did daily 90% water changes for the last 3 days. I have used this medicine in the past quite a few times both on bettas with fin rot and other tropical fish, and have had no problems at all. This is the first time I have used it with her, and she has been breathing very quickly. Today when I woke up she was staying at the top vertically and kept pratically jumping out for air. I did a 90% water change real quick to get the tetracycline out of the water and then ran to walmart and got an air stone and put it in her tank. She is still breathing quickly but no longer hanging around at the top gasping. If I go near her tank she begs at the top for food like usual - she's a very big eater and begs a lot and eats a lot without having any swim bladder problems but seems to be much hungrier lately. She is being social and interacting with me. I put some pellets in and she gobbled them up. I am worried though, about giving her the 4th dose which she is due for tonight (which would complete 1 full round of tetracycline). I think it would be best to stop giving it to her but my concern is that she looks like she has a lot of improvement today, red streaks are fading to pink and barely visible, her eye is better, fit rot has stopped progressing. If I take her off the tetracycline before completing all 4 doses, is it likely that she will start to get symptoms back again? I don't want to cause antibiotic resistance and have her get worse again but I don't think she can handle this medicine. Has anyone else had a betta who had breathing difficulties while on medication and what did you do? Also has anyone had an experience stopping medication too soon and did your betta get worse? Would it be ok to just put the 4th dose in since there is an air stone now?
my other thought is, is it possible that just being sick could cause her to breathe more quickly regardless of whether i had put medicine in or not?
Thanks for everyone's help!
