Predator for Fry/Juviie Control

So, as some may know, I'm having a N. Brichardi over population issue. I think I have close to 200 of them in my 265G and need to get rid of them. I actually want to get rid of everyone of them including the adults. If someone wants to come over and catch all of them and take them, that would be great. May be I will have to catch all of them and take them to a Petco. Calvus are not even touching the the small fish. Any fish I can consider that would help with the population control? Thought about an Oscar, but I want something I can keep in the tank permanently.

An off the wall solution:

Tank bio overload

Small CLs can get into caves and consume eggs and fry, and do it at night. Big CLs will try to squeeze into rock caves too small for them, so make sure your rock caves are stable. It's easy to thin out the fry. In your next WC, remove some rock and watch your big fish happily gorge on the nutritious live food.

No, it doesn't help. I have 2 of these guys, Lamprologus elongatus and 5 leulupi in the 75. These predators have no size constraint to enter the rock caves but the aggressive Daffodil parents won't allow them to get close. Some of the larger Daffodil siblings also help defend the nest.

I think only small nocturnal predators like loaches will work as they will prey on the fry when the defenders are sleeping.

I can only speak for mine and they have done a great job of population control and the Pulcher parents are wild caught and diligent defenders. They keep the Nkambae on the right side of the tank but the Nkambae must be getting their share as I am many generations in and there are only about 20 juvies.

My pair that started spawning were not successful keeping the spawn alive for first 10 or so spawns. Then they were able to keep a very few alive in one spawn. And then they were successful keeping more and more alive. And then, as mentioned above, as the surviving fry grew, they started chipping in and now, I wouldn't be surprised if well over 50% of the spawn survive. I now have at least two pairs spawning in the tank and NO fish in the tank no matter what size even try to go near the fry or juvies.

Sounds like the aquarium version of the Kardashians.

If you can find a plagiostoma spiney eel they're egg eaters. Stay small, around 8-9" max, and unlike most other eels they don't bury themselves in the substrate. They will eat any eggs in the tank, right out from under the parents protecting them.
