Some Advice for small aggressive fish.

[TetraBotia]

Butterfly is a good suggestion... Puffers too...

Nobody has mentioned some of the Killifish. Some of them are really dang aggressive, and will eat live foods from the surface (insects) as well as fry from just about any small fish. Might be kind of hard to come by, and they are sometimes spendy.

Anything that is going to consume a feeder goldfish in a bite or two is not going to live in a 10 gallon very long... so, you have to take that into consideration...

And come to think of it, nobody has mentioned any of the crayfish... that might do for ya!

i think most puffers grow to 12 cm's , so thats probably not your best idea... i have one in a 40 gallon tank. how about a tiger barb? they are notorious for chasing after fish and nipping fins... very fast fish they killed 4 mollys i had.

HAHA your funny! Dwarf Puffers get no larger then 1.5cm. I think you have something else.... What do you have in your tank with this "12 Inch Puffer?" I would like to know considering there are only 2 species of freshwater puffers that get above 12 inches. Tetraodon lineatus, Tetraodon mbu. Both of which are very hard to aquire.

10G is too small for most crayfish too...
