it will home 1 snowflake eel,3 orange monos,1 archer fish,1 small silver datnoid and three to four crabs it already houses 1 dragon goby and two crabs the filters are 1 tetra internal filter that filters forty gallons,a small sponge filter attached to a aireater and im going to get a large bio wheel filter that filters 50-60 gallons and there will also be mangrove seedlings.
I wouldnt consider that to be good filtration, but adaquate if you change 50% or more of your water weekly.
If you have the funds get an Aquaclear 110 instead of the biowheel (penguin 350?)
