I have two dwarf gourami, one orange and one iridescent blue, over the last 2-3 weeks I have noticed the top fin of the orange seems to be turning blue, is this normal?? I have looked on many sites but found nothing similar?
They are both males if they show strong coloration. Females are silver. As for the orange male getting a blue stripe - he's just turning into a normal red dwarf gourami. Most of them have that blue line, you can see mine has it in the photo in my sig.
I'm assuming you're talking about my betta! Thank you so much, I think he's lovely too. If you're asking about his housing, all of my bettas are in seperate tanks.
