I started to think about just how much water is needed for maximum fry development and after a point are you just wasting water and time?
There is the assumption that more is always better. At some point in time other factors will limit fry growth such as the metabolic rate of the fry.

Both groups were about 1-1/2 inches SL when I got them early March. Those with the three caves are now about 2 inches SL. The ones with the overgrown jungle average 2-1/4 inch SL and are out in view a lot more often (dithers vs. cover is another question to be asked). Regardless, there's an obvious size difference.
Guys, please send me some data. Without it we are still working with 'voodoo and tribal knowledge'.
The set-up is the same in the second tank with only two differences. There is only one cave, and that tank is overgrown with Najas guadalupensis. Both are also on the same central system, so water quality doesn't vary much between them.
