To reintroduce the best bet is to turn the lights out and rearrange the tank. Once the Oscar puts on a few more inches (which won’t take long) it should go better and be able to hold its own.

I noticed that the severum is shaking his head quite often. Also i spotted some white spots on his fins but no where else in his body. Can someone please take a look? Is this normal?C185E211-C812-48E1-BF25-5C4B2D79487B.jpeg

I do have also 4 severum. They are in a constant battle since I bought them. The only good thing is that there is very little fins tearing and they all eat like pigs. In 10 days I can see growth. I just managed to stabilize the tank. I would like to know if daily water changes up to 10 gal in 75 gal tank is going to be ok.

those daily water changes are fine. I do the same for my 55g.

Sometimes these immediate pairings work out okay but sometimes they go sideways. The “newness” wears off and the pairs realize they aren’t compatible, usually after a disagreement over the care of the eggs or fry, and one of the fish ends up shredded. If you are isolating them with no dithers at all, make sure you have plenty of cover and hiding spots in case one needs to get away.
Agree.

What I don't completely agree with is the earlier comment that it's common for cichlids to pair up immediately-- and I have decades of experience. That may be true of some species, but not all. Some species can be picky about pairing, including Heros species. It's a mistake to think you can put any two of any new world cichlid species together and expect a compatible pair. In some species they're just as likely to kill each other, in some you may have to take your time introducing them, starting with a divider. In some species how it goes will totally depend on the individual fish-- getting an instant pair with these can happen but there's no guarantee. Heros (severums) are like this, some acara, some geos, and some other species can be like this. Some will pair quickly, some will pair after a period of time, some will pair and spawn a time or two, even produce fry, then lose interest, or the bond may wax and wane. In some cases I've had Heros pair basically ignore each other in a cichlid or Heros community after a brief or loose pairing (these were types where male and female were easy to distinguish by facial markings), while some will fight afterward. I've had all of the above happen with severums.

Right now I have four A. metae. A day after I got them they split into pairs, one pair bonded closely and has mostly stayed that way, the other not so much. For a while I had two pair defending territories at opposite ends of the tank. The second pair bonded briefly, cooperated closely in defending their end of the tank, then waxed and waned for a while until the male lost interest. He's not aggressive to his former female, mostly just ignores her.

You can't extrapolate pairing and breeding rules for all SA cichlid species, or for individual pairs, from experience with some of them.

I have two severum in a 180 that have shown spawning behavior twice. I think they are both males. It seems like there are 3 possible outcomes when pairing severum, regardless of gender. They ignore each other, they kill each other, or they spawn.
