so planted is out. could do silver dollars. i like the look of the hrp. are frontosas a viable option? i dont nessisarily eant to do a biotope set up and frontosa were my other main want for a fish. i like firemouths too. My 180 has a school of 25 or so corydoras, as well as 5 angels. if i could keep fronts that would make me super happy.
