For the last two days, one of my angelfish has been acting rather peculiar.
What's causing him to act this way?
Oddly, his actions are those of a breeding male. One who has staked out the best spot to fertilize eggs. One who knows he can defend the eggs and babies from predators. The dark colors intimidate other fish, because it shows he's ready for a fight.
The only problem is he doesn't have a mate.
There are several female angels in the tank. Maybe he's trying to impress them. I will be on the lookout for some mating in the upcoming days.
