No Baby Tears in my tank; probably not sufficient light from what I've read. The substrate plant in the 90g flooded Amazon is Pygmy chain sword
, Echinodorus tenellus; in the 115g is another similar Chain Sword
, E. quadricostatus on the right, and E. parviflorus (dark green) on the left. In the 70g SE Asian there are crypts, developing Aponogeton (about a dozen from my parent plant), and Wisteria
I try to design the aquarium geographically around an idea. The 115g is an Amazonian riverscape, so I have bogwood lying on its side more, and more open substrate and this tank has the majority of Corydoras that feed from the substrate, so I can thoroughly vacuum the open gravel to keep it clean for them. The 90g is a different concept, a part of the flooded Amazon forest, so the ground is thick with plants as the forest would be, with a small open area where again I feed the Corydoras and Farlowella. The SE Asian isn't really done yet, just a mish-mash of plants.
The idea in all this is that the aquarium should be designed around the fish that will live in it, to provide what they need, and all fish are different. An obvious example is a pleco, or my whiptails and farlowella that need wood; or gourami and betta that need floating plants. One doesn't have to be strictly biotope, but generally geographic is one way; or a combination of different geographic areas but with fish that still have basically similar requirements, like forest tetras and forest rasbora together in a well-planted tank because both come from such environments, or Corydoras and loaches that all come from streams with sand or fine gravel, wood and/or rocks.
