i have a 4.5 inch grammode and mean as all get up. he flares at my 2 large jags. the only 2 fish in the tank that he doesnt flare at is my jar and butti. my largest jag could probably bite it in half but grammy dont care. lets see em peeps.
I would say the Grammode allthough smaller will do fine in a tank with larger and more aggro mates (not many of those tho..) I had a 4" in with Jags, Tex, Mota, Red Devil, Male Cons, and did he more than fine. Now I have mine in a 150 with Festae, Mota, Convict Pairs, and dithers.......He does fantastic.....
Now here is some shots of my Lil Guy.......(sorry bout the glass, had to get shots up as I did not want to be seen as all talk, no grammode! LOL!)
