The fish are beautiful and bright blue color. Thank you for giving such good points and explaining how to avoid bullying in Discus tank. This will help a lot, as I have observed the same behavior in my tank.
Thanks 🤗.. Black background is bad for red, orange or any other colored discus. But, for blue , cobalt blue and blue snakeskin black-background bring their true color.
I always prefer DIY food for discus. This will be helpful. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IOytsY-O3Kc.html Plz note DIY food are messy. As long as u r daily syphoning poop & uneaten food . U should b good. Vibra bite is a good food.
