These two have been very unsuccessful in raising any fry countless spawns, free swimmers then they disappear due to tankmates. The male beat the female so I separated them. After 6 months after I add her back and they instantly paired again. No aggression. Now in the 150g causing trouble lol. In the FTS you can see the area they claimed. I’ll say I have never seen a stronger bond in a cichlid pair. Even with other monogamous species..
