Well, I guess it’s just one of those things you have to deal with. My male Bellus Angelfish is the biggest fish in the tank, but looks like someone put him in his place last night. Not sure who it was. There are a Powder Blue and Purple Tang in there, but I’ve never seen them show aggression towards anyone. The most aggressive fish is the female Bellus. She’s not that big (3”), but she’s constantly chasing others. Wonder if there is a marriage squabble going on. She does look like she may be carrying eggs. She’s getting quite pudgy around the middle. Maybe she’s just telling him to back off, because she isn’t ready yet. He’s always chasing after her. Also, don’t know if those are bites or scrapes from running through the tunnels too fast. His other side is scratched up as well.
