Would my tank fit the description? - Fast moving, oxygen rich water
I'm looking at a different types of fish... and some are described as fish that like fast moving, and oxygen rich water(kukli, alligator loaches, otos..etc).
Would a 55 gallon tank with two AC70 filters, java moss, and java fern be considered to have fast moving, oxygen rich water? Or do all these fish require the extra equipment(airstone/bubblers, powerheads...etc)?
Or would such a tank be good for those that require slow moving water(asian stone mini catfish)?
