I'm thinking about getting me some other fish, for companion.
Alex what could be an option?
I kept 5 of my A.Rostratus with bunch of T.Helleri, I am saying kept, because I lost most of T.Helleri, I have bad luck with them. But they did fine together, no problems at all.
I also have school of Dimand tetras, and group of Otapa swords. 3 red tailed shark there too, being a very good scavengers.
If you interesting about my opinion for your tank, I would add large group of nice genuine Xiphophorus (sword tails) species.
Don't put other cichlids, that you already have, unless you want to add more A.Rostratus
, they love to be in the large group and they look and behave amazing together.
I can't suggest red tail or rainbow sharks, because I am not sure if you like to keep CA tank without mixing fish from other regions, but I found red tailed sharks very useful additions to all of my tanks for years. They don't bother my fish (even many sources suggest that they are aggressive protecting own spots). If they do fight, it's between themselves, until ranking established. They also don't hunt cichlids fry I had and clean places where other fish can’t get.
As for the Tetra's again, if you planning to breed A.Rostratus, tetras may prey on fry and make shy A.Rostratus uncomfortable all together even for breeding attempts, but it's just my assumptions, I didn't have chance to see Rostratus breeding behavior at all.
So, yeah, get more Rostratus and bunch of green swords
Let us know, how you make it out.
