This biotope captures a clogged channel in the late-fall watershed of the Reedy River in Upstate South Carolina, a key tributary of the Santee River Basin. The landscape is shaped by iron-rich red clay soils, carving winding river channels. The red-orange riverbeds sparkle with mica, worn from the erosion of common metamorphic rock in the region. During fall, deciduous trees shed their leaves and drop dead branches, which accumulate in the shallow channels to form naturally occurring debris dams. These seasonal obstructions trap organic material and sediment transported from upstream, creating complex microhabitats to provide shelter and foraging grounds for small fish and invertebrates. https://scnps.org/wp-content/uploads/2024/04/SC_NativePlants_Family_RegionalAbun_20220108.pdf https://www.greenvillecounty.org/LandDevelopment/pdf/RiparianBufferManualFinal.pdf

This is an excellent example of a North American biotope, focusing on microfauna and seasonal representation, which is very different from tropical biotopes. Honestly, the first impression is of a barrier of branches and accumulated leaves as seen in nature, which is the main objective of this biotope aquarium. Great job!
I have seen these miniature, natural, river dams or clots in the wild and this biotope aquarium recreates them very accurately. What is more surprising to me is the fact of noticing these clots (micro habitats) in the wild and then having the idea transported into a biotope aquarium. These ideas, which surprise me, which make me stop and say: "Wow, why didn't I think of that?" is what fusing nature with the aquarium hobby should be about!
This display deserves top marks from me! The natural aesthetic of the substrate, the clearly carefully-placed, yet authentically-organic placement of the branches, the use of minimal planting, placed so that they look as they would in the wild, it all adds up for me. As a biotoper who focusses on fishes and plants, I think it takes a degree of courage to submit such an entry, without fishes or even large molluscs, just a few snails and tiny invertebrates and very little planting. I get the sense the author knows this habitat well, which has translated itself into a display which looks like a genuine slice of nature. Well done!
