Ok now you've done it!.... we need pics to see the progression. We're all addicted to that sort of thing you know!
Oh that is interesting... I suddenly had an "ah ha" moment from what you said.... :shock: Why I didn't get this before is beyond me.None of the plants you listed are out of the realm of doing well together. Placement is important. For example, shade low light plants ( Javas, Crypts) with moderate light plants. The highest light plant you listed is the red ludwigia. That should be in a position to receive plenty of light.
