I Created a Mini Ecosystem Fish Tank - 120 Days Evolution

Daniel developed a 10-gallon planted aquarium that became a self-sustaining ecosystem containing snails, cherry shrimp, and neon tetras, shifting from an initial plan of plastic plants to live plants and minimal maintenance.

Tank challenges included a betta fish attacking cherry shrimp leading to its relocation, and neon tetras successfully treated for white spot disease with medicine that temporarily turned the water blue.

The tank experienced extensive plant growth, spontaneous snail proliferation feeding on plants and vegetables, thriving shrimp breeding, and the emergence of tiny gravel worms.

Aquarium setup, maintenance, and ecological stabilization.

Aquatic livestock health, behavior, and tank compatibility.

Plant development and invertebrate population dynamics.

Daniel set up a 10-gallon aquarium with gravel, plants, a betta fish, neon tetras, and cherry shrimp.

The betta fish ate a cherry shrimp and was subsequently transferred to a separate tank.

Daniel administered medication for white spot disease to the aquarium, turning the water blue and clearing the spots on the neon tetras within one to two weeks.

Tiny worms appeared in the gravel.

A snail emerged from its shell, spun and twirled, re-entered its shell, and landed on a leaf.

Daniel ceased regular water changes and gravel siphoning, switching to topping off evaporated water and wiping algae.

The precise plant species purchased for the tank remain unidentified.

The exact source and origin of the snails appearing in the aquarium are unknown.

The snail population is estimated between 30 and 50, and future population management remains undecided.

The cherry shrimp count is an estimate of about 30.
