I currently own a CT betta named Suzuki who lives in a 9 gallon filtered, heated and cycled tank with some live plants. I feed him Hikari Betta Bio Gold pellets once a day (3-4 pellets) and do a 33% water change once a week.
He currently has mild fin rot from the store I bought him from which will not go even after 2-3 weeks in his new home. I've even tried doing extra water changes (10%) every day for a week. After Scout camp, I came back on Friday to find two of his "spikes" short with white tips unlike the rest of the "spikes" which have black tips. I was shocked that the fin rot had moved so quickly that I immediately started to treat him on Myxazin. I finished the course on Tuesday 31st July and did a 33% water change the next day. I know that I probably should have done AQ treatment first rather than medication but I was very shocked by the state he was in. The medication hasn't made a difference.
The thing is, when I look at his fins from underneath him with strong lighting in the background, his "spikes" appear to have transparent tips. I know transparent fins are supposed to be re-growing ones but I find it hard to believe that they are healing when he still has black tips. His fin rot hasn't really got worse apart from the white, short "spikes", in fact, some of the tips don't have black on them anymore. He's not lethargic but he has calmed down since I first got him.
So, are his tips transparent because they are re-growing or is it normal? What can I do to finally get rid of his fin rot? Why did two of his "spikes" suddenly change?
Thanks in advance!
