Thanks! :D Not really, as you can see it has 2 small HOBs astride the dividers running about 2/3 speed. It gets mechanical as well as biological filtration. You don't vacuum or stir the substrate where the plants are, and only lightly on the surface of the rest. I do a 50% change once a week, each section has a Zebra Nerite for possible algae. Bettas are darn near hand fed, so there is little if any food left over. If for some reason you get way too much in there, a turkey baster suctions it out. If anything falls in the plants, the fish love hunting in them, and of course poo is a great fertilizer..
Wow, thanks everyone! :D Yes, the "guys" love their sections, they hang out in the plants and pop out whenever I come by. You can see my DTHM on the left near the bottom as well.
At the back is Rotala Indica and Rotala Wallichii. The midground is Telanthera. I'm looking for a foreground -not HC, it floats away-has to be dry-started, nor dwarf sag or hairgrass. Maybe glosso or dwarf water clover if I can ever find it...
I used craft mesh (brown for natural-ish look) and report binders to DIY the dividers. Sort of like this tutorial: http://www.tropicalfishkeeping.com/d...ividers-21866/ . I siliconed the binders in on both sides and the bottom, and put one across the top. Very stable.
