I Created a Mini Ecosystem Fish Tank - 120 Days Evolution

A planned simple 10-gallon tank became a dense ecosystem after adding gravel, ornaments, plants, neon tetras, shrimp, and snails. The betta ate shrimp and was relocated; five cherry shrimp became roughly 30, while 30–50 snails appeared and multiplied. White spot disease cleared after medication; plants, bacteria, worms, shrimp, and snails recycle waste, leaving algae wiping and water top-ups.

His intensive water-changing routine gives way to trust in a self-regulating ecosystem.
