Monster that fits in a 20

[Fishyfan]

A few indian dwarf puffers would make some awsome mini monsters for a tank that size! Its pretty fun watching them hunt down their food.

Good luck with your tank

I wouldn't keep either one of those in a 20. I've seen arowanas reach close to 40" and oscars @ about 18". You many be able to get away with one or two pictus cats or columbian sharks if it's a 20 long....

columbian sharks usually get fairly large

20 gallons? dude get some GUPPIES!

no true monster fishes could possibly fit in one.

but on another note: whats the minimum size tank for having a monster tank?

that is a complex question in a simple sentence.

all depends on the species of fish

Great answers to the question (well a few that is), ROCK ON!!!!!If the recomended tank size is 100 gallons , if you can afford it , buy a 200 gallon tank. You and your fishes will love it even more. BIGGER IS BETTER!!!!!!!!

you can get like three exos or maybe a small pair of cons!!

You could keep the monster's dinner in a 20 gal tank!!! Oscar's or arrowana's need lot's of space and do not belong in a tank that small, Oscars need at least 55gal arrowana 150gal or more!!!
