does anyone know might this front might e cos he has a different facial mask/stripe to the rest of my burundi, and also has a slight yellow tinge in his dorsal fin...
If this is a repeat, let me know and I'll delete it. Here's a pic that shows the regional differences in various front strains. The darker upper front is a (WC) Samazi varient and the lower front is (WC) Maswa varient.
