Hi this is my first post on here but I have used lots of information found on here to learn about betta care.
My fish Big Blue is sick. His condition was caused by poor water quality and exposure to too much algea.
He was treated for Velvet two weeks ago and showed some improvement. His appetite is fine and lots of his color is back but his head is still dark. His breathing is better and he's greeting me when I walk in the room but I am super concerned about him. He made it through my week vacation and upon my return i realized he needed an antibiotic for secondary infections (red gills, rad patchy spots on him) so I bough Tetracycline yesterday. I gave him one round of the meds last night around 10:30.
After testing his water, I discovered that the ammonia level was high so I put his carbon filter back in to try and reduce it overnight. I know it's not recommended with the antibiotic but I didn't know what else to do to start lowering ammonia levels immediately. I am about to run out and get something to lower the harmful ammonia levels until I can get rid of it entirely.
This morning, I noticed the white ring around his eye. Is he developing op eye?
Is the discoloration on his body a fungal infection?
Should I do a water change?
pH is 7.4
NO3 and NO2 levels are )
ammonia is approx. at 2.0 ppm (which I know is a problem)- it has reduced since last night with the replacement of a carbon filter.
please see photos, what is wrong with him? What should I treat first? I have pictures from a few weeks ago if it will help to view his progress...
someone please help me, i don't even kill bugs and if I let this fish die I am going to feel so so so bad. I feel like he's suffering and I want to help him ASAP.
