That's it. I'm sick of all this "benign fish" bullshit that's going on in DF right now. Carp deserve much better than that. Much, much better than that.
I should know what I'm talking about. I myself commissioned a genuine carp in Mountainhome for 2,400,000 Dorfbucks (that's about 20 dorfs) and have been practicing with it for almost 2 years now. I can devour entire sieges with my carp.
Armok spends years working on a single carp and folds it up to a million times to produce the finest fish known to mankind.
Carp are thrice as fast as European fish and thrice as mean for that matter too. Anything a pike can bite through, a carp can bite through better. I'm pretty sure a carp could easily bisect a knight wearing full plate with a simple vertical chomp.
Ever wonder why the kobolds never bothered conquering Mountainhome? That's right, they were too scared to fight the disciplined dorfs and their carp of destruction. Even during the siege, goblin soldiers targeted the carp first because their killing power was feared and respected.
So what am I saying? Carp are simply the meanest fish that the world has ever seen, and thus, require better stats in DF. Here is the stat block I propose for carp:
[CREATURE:FISH_CARP]
[NAME:carp:carp:carp]
[TILE:224][COLOR:3:0:0]

[AQUATIC][UNDERSWIM][IMMOBILE_LAND]

[STANDARD_FLESH]
[HOMEOTHERM:10067]
[SWIMS_INNATE][SWIM_SPEED:500]
[SPHERE:WAR]
[SPHERE:DEATH]
Now that seems a lot more representative of the destructive power of carp in real life, don't you think?
tl;dr = Carp need to do more damage in DF, see my new stat block.
