Hey, sorry to post this question inthis forum but i always seem to get the best answers in this forum. i have a 20 gallon long tank laying around and i wanted to put an agressive fish that can eat live food in it. i already have p's in another tank so i dont really want more p's. i was thinking some exo's, puffer's or convicts. does anyone know if my tank is big enough for these particular fish? if so how many of each type of fish would fit (not all of them i will pick either or this will be a species tank) does anyone have any other suggestions besides what i listed. how about a flower horn? please help i want to buy some fish soon 
thanx i appreciate it
bye
