whats the most brutal mean fish ever?

Do you want a school of Pacu’s in a 10 gallon tank? I would think you mean you’re getting a tank that’s about 100 gallons for each Pacu and you’re feeding them the Oscars as some high quality fish food. When they get full grown you’re looking at needing 150+ gallons of water each with lots of water changes.

I don’t think 2 Oscars will be happy in a 10 gallon tank by then selves.
 
HAHAHA, two oscars in a 10 g. are like me putting a smallmouth bass and 2 sunfish in 29g. Only bad part about this is that it is true.........


No worries they are only staying there for a week. Had you guys worried didn't I.
 
Just keep in mind mulch that some fish mentiioned such as dovii and pacus - these fish do not require 150 gallons each, they require at least 300 gallons each!! And even then, pacus get too tall for most aquariums.
