Agressive fish for a 30 gallon?

JHK30

I have a 30 gallon that has community fish in it right now, but I have a ad on Kijiji Toronto Classifieds: Free Classified Ads for Toronto, Ontario to sell them and once they are gone I want to buy some aggressive fish that will live in a 30 gallon. I want them to be cheap. (max 10$?)

I wanted oscars but they need a lot more room... whats a good fish that will fit?

I want something bigish, and aggressive like if you put your finger in the tank they would attack it.

FishFreak95

k i did more research on em they could destroy your finger lol. Found out u would need 100gallons. ill keep looking

lol ok thanks!

a snakehead fish! you will be able to keep it in there for a while but later you would have to upgrade to a bigger tank. There the most aggressive fish I can find but they eat several feeders a day which might end up being expensive

yeah I wouldnt mind giving the fish feeders for treats it would be awesome! but a couple every day? I cant hold them in a tank and I cant go to the store everyday for some feeders.. (this is where a fish pond would come in handy. hundreds of fish to feed them)

FishFreak95

breed feeder guppies maybe

Watch out though, snakeheads get huge and they're illeagal in alot of places.Here if you catch one in the wild you have to kill it on the spot.
