Especially in the Firemouth Cichlid realm of our tiny little aquatic animal kingdom:

They spawned about 3 weeks ago, and it’s been hell for the others in that tank ever since. I moved the smaller guys downstairs but the remaining 7 fish, including a Jack Dempsey of equal size to the mother Firemouth have been pinned to the far west 6 inches of the tank ever since. At one point early on they were being held against their will in just the one top-rear corner.
My fish guy in Boulder says Firemouths are pretty good about being aggressive towards their tankmates compared some others, and nobody’s been hurt yet, so far so good. There were literally probably over 500 fry initially. It looks like about half of them have since been predated. We’ll see how many remain to be captured and sent off to the fish store before they overrun this 190-gallon tank.
