Thanks so much that is really helpful info, I will start looking at 180 and above size tanks for my aro regardless if its silver or black. I'll probably post a wanted post for a used version of sorts.Satan's Goldfish;3135500;3135500 said:Well, a silver aro could grow to 40" in time so you'd need much large than a 125 after it'd out grown it! 300+ with plenty of turn around room. My silver is in with ca/sa cichlids with no issues, however i think there normally is problems with compatability on aggression from the cichlids towards the aro from what i've read on here. P-Bass are fine with them, and with the size of tank required for the aro, they'd fit nicely!
Aros have no issues with Plecos.
As for Black Aro's not growing as large, i'm not sure if that's true or not but i have a friend with one and it definatly requires more than 90gal! I did read somewhere that the silvers grow the largest/longest out of all the aros, blacks have a very similar body shape to them compared to asians or jars so can only assume that it's still going to break the 24" mark.
African cichlids do require different water conditions to SA fish, but never kept any myself so don't know what the differences are!
Hope that's of some help anyway.
Gonna have to really make this aro dream come true!!!!
