hello again members. about a month ago i purchased a second betta. he is a beautiful steel blue, hence the name: Remington. not long ago i noticed a "thing" on his ventral fin. i did some research and think it is cauliflower. the problem is that i cannot remember where i read about it, nor can i find the web page again (i forgot to bookmark it). so, what i'd like to know is this: am i correct in thinking that cauliflower is a viral infection and that Remington cannot ever be placed with other fish because the risk of infection is to great? i had wanted to place my two males in a divided tank, but...also, i think i remember something about removing the growth, but am not sure and do not want to do anything until i am positive. other than the "thing" on his fin, Remington is doing wonderful. he is healthy, active, eats well, responds well, ect. if i remember correctly, he should live a normal life, in spite of the growth. i just hate to see that thing on his fin. any help, suggestions, ect.?
