Thank you for taking the time to respond duanes , I have been keeping fish for quite some time but have been experimenting with my current setups, almost all these fish are movable as I have 4 tanks I can rearrange at my disposal, with that being said, I want to keep the arowana, clown knife and some more aggressive cichlids with them. My LFS has been my number one stop for information as they have helped me set these tanks, however there knowledge is proving to be unhelpful. What cichlids do you recommend keeping with them? I have a green terror, Texas, eba, albino Oscar, and geo balzani growing out, as well as a gold sevrum, I don’t mind splitting them ca and sa just struggling on finding companions that at hardy enough but not too agressive that share the same water condition requirements.To me, you have two separate groups of fish that don't belong together, reguardless of who did what at the moment, and that in the future may cause grief..
There are the South American soft water, low pH species (pH 7 or below).
The sveni(?) which do best a shoal.
The Cichla
The SDs and Arowana.
On the other hand, you have the Central Americans, all hard water, high pH species (pH around 8,
the FM (which belongs in a shoal of their own kind (4 or more FMs), and tends to be aggressive if kept as a lone individual)
the Herichthys (also volatile)
The salvini (another volatile cichlid especially as it matures.
And of course tha others that (to me) don't go in either cichlid biotopes at all.
My choices ultimate would be based on the type tap water I have.
That “sveni” i think is actually a Acarichthys heckelii sold incorrectly
I wasn’t aware firemouth did better in a shoal, I thought they were like most of the others I best keep as just 1 so they don’t pair up and get worse, good to know, I don’t have room to keep 4 in this 150 should I pull him out? He isn’t bad yet
I have looked at chocolate cichlids, vejas, Dempseys etc, as far as I was aware the aggression is very situational, you may have a chill one or he may be the devil with most of the groups I’m after.
