Ok, I have a 5.5 gallon. I am really stuck on which to get! habrosus is bigger, but .50 cheaper ($2.50) so price doesn't really matter much. I'm rescaping soon with potting soil and a black sand cap, microsword carpet and othe plants, and azoo palm filter. Temperature is 80 F and I apparently have very soft water (from the Catskills to Manhattan). It is all cycled by the way. No ferts or CO2, 14 watt fluorescent desk lamp, yellow. Which would do best and how many? Which is easier to breed in these conditions?
