predatory fish

  • We are currently upgrading MFK. thanks! -neo
Actually....if you can find one....a South American Leaf Fish (Monocirrhus polyacanthus) could do reasonably well in a 12 gallon tank. Bear in mind that these fish almost always eat nothing but live fish and will starve to death before they take anything else.

Twelve gallon tank...I would say channa gachua...all by it's lonesome....get's to about 4 inches...in a bigger tank, i.e., 40 gallon, it can grow to 6-8 inches...Very hardy too, air breather so you don't need filtration, low maintenance, can survive in a stagnant water, but likes also running streams...so take your pick and splurge. Undergravel should be enough..and will eat pellets.
 
forget it bro' these guys hit 10in inside of 3 years



perhaps a yellowtail cuda max at 6-7in compaired to the red baracuda at 10in


theres a **** load of preds fit for 40 or 30 gallon but not much for a 10-12g
 
African Butterfly fish is all I can think of that won't outgrow the tank, maybe a dwarf pike, they stay small if I recall. Small puffers are nasty as hell, and will kill all sorts of stuff.

An african underwater frog isn't a fish, but it will fit the bill of a predator.
 
If you could find them, you could possibly keep a pair of these guys in there:

They are supposedly mean as heck and love to tear up some small feeders. You can find out more here: Pike Killifish

If not, a group of dwarf puffers would be cool as well. They only get a little more than an inch long and would survive just fine on frozen foods.
