The embers are getting braver at last
The Ember Tetras are near the bottom for good reason--they are stressed by the overhead light. This is common with most forest fish species. Floating plants solve this problem, I suppose taller plants might too, depending.
There's a couple floating plants plus a third which is an oxygenator arriving tomorrow.To help them venture out more, I would suggest areas of cover using floating plants. Byron, who was great at promoting fish wellbeing, pointed this out to me when I kept embers a few years back in an iwagumi scape (stupid decision on my part).
