Nanochromis Splendens

I have a male and 2 females. The male I purchased back around May with a female which I lost in July. I added the two females in September. The male did not play nice so I moved him to a separate tank. Each female is in a separate tank as well. All 3 being housed in 29g.
Today I tried reintroducing the male into the original tank with a female. He immediately went on the attack. At one point he had her by the tail trying to shake her. She is now hiding up in the corner behind the overflow sponge while the male patrols the tank looking for her.

Male, back in May. He is the size of my ring finger.

Moved the female.

Are there a lot of visual barriers and caves/holes to hide in.
Do you have full tank shots of the setups?

The first is from during setup. Under the rocks I placed egg crate and removed a 1in x 2in ish section to make a cave. There are crypts planted all around the rocks down the full length of the tank.
This is the original female poking her head out.

That might work.
My experience has been, what looks like hiding spots to us, is open space little fish highways in between. Leaves tend to umbrella and leave open space below which is where the fish travel.

What ahs worked for me is setting up a lot, about 6+ caves for a pair of aggressive fish. Then I would make barriers the went high into the water column so a patrolling fish cannot merely swim over it to attack the hiding victim on the other side.

For instance, the rocks you have, I would tend to place the closer together and pile more on top. Then, plant around that. I would do that again on the other side. In between a forest of val or crypts could make a covered passge.

Here are some recent pictures cockroach

That rock "pile" should give the fish being chased a bit more cover to swim through, around or over. The more options the better.

The juvenile rainbows are in a 29g next to the male which causes some territorial flaring.

Pretty fish.
How's the aggression going??

I'm still running a frat house and a sorority. Been to busy to try again.
