Is the Vieja Argentea aggressive.

  • We are currently upgrading MFK. thanks! -neo
My 11" argentea is wonderful with all fish except with cichlids similar to his size.
 
Just out of curiostiy clockwork what fish do you have in your tank

The link to the tank is in my signature (click it).

-2 argentea 6" and 4"
- 5 freddies 3"-5"
-Pair of cutteri

That is temporary growout stock because I bought the two groups at 2" fish. They are getting too big now and I have a 125, 90, and 60x18" tank to move around in. I definitely don't think they could live together long term even if I had a big enough tank for all of them.
 
I thought that Black Belts were really aggressive.
They can be, but in my experience when a fish in the cichlid world is less than half the size of a large aggressive cichlid they're often ignored or not as vigourously chased. The larger cichlid doesn't see the smaller cichlid as a threat. Meaning the little cichlid is no threat to mating rights or food source or even territories as in what can a small juvenile cichlid do to a large adult. Cichlids close in size fight for these things, but when there's such a large difference in size, it's obvious whose the alpha and whose gonna get his way. Also luckily most Vieja are vegetarians so the adult won't even look upon the juveniles as a potential food source. Plus Vieja have in general proportinitely small mouths for their size so they couldn't even eat the juveniles in the tank unless they were really small. Size though won't always stop aggression as even a small growing cichlid will often challenge larger cichlids for territories and such if both are adults. For instance if there was a mature convict cichlid in there it would probably be on. Lol! At least that's what I've experienced, I guess aclockworkorange will give you a more definitive answer in his case.
 
My 11 inch Argentae was downright mean. I could not keep anything in a 90 gallon with him. Not even large common plecos.
 
My black belt male completely ignores everyone except his female. It is 100% size based. My cutteri are "convicts on crack" and run the tank. I'll take video here in a minute of them interacting right now and upload in a few minutes and explain the situation more.
