I have the opportunity to get some young frontosa for a new 125 gallon 6 foot tank that I am setting up (filled partially from an established tank along with a HOB from an established tank that i'm tearing down... I'll add another filter soon to increase filtering capacity). I basically can get as many as I want, so how many youngsters can I fit in there to grow up together and form a breeding colony? I believe he told me they were burundi, but i'll need to double check...
