Hi everyone, I'm new to this but seem to be having the same problem as jriley... which is how I found this site.... In hope to get answers to help one of my rescued bettas, a beautiful orange & red one!
The day after rescuing him, & changing his filthy bowl I noticed this patch came on him (in 2 places)... On the tail & one at the base of the top fin, after vigorously attending to him & the others (4 in total) I treated the water with a all in one treatment that covers fin rot as well as the ick, but the one spot on the tail remains... The other one not quite as noticeable (they sometimes has an irredescent appearance to it!)... even the edges of his fins.
Please if anyone can help... I already had 4 bettas of my own but I couldn't stand to see them in such conditions...wouldn't want anything to happen to him after this long struggle
