well i got another reddevil for a birthday present along with a 40 gallon.he is about 6 inches long.For filtration i have two aquaclear 200 filters.For subtrate i have blue gravel.Does this filtration have a effect on growth.
I think the healthier the water, the better the growth. If better filtration AND tank maintenance helps, which it does IMO, then healthier water, healthier fish.
