The Escanaba River tank is a 254-liter recreation of the scenes I’ve experienced over the years along this river. The specific environment represented is a calm pool that forms beside the rushing rapids.

To build the base, I created a custom substrate mix of dirt, clay, and gravel, providing a firm foundation. Additional layers of substrate were added to sculpt the riverbed and form ascending banks. Large, smooth rocks are placed throughout the tank to reflect the polished rock walls of the Escanaba, shaped over time by fast-moving water. Gravel and small, rounded stones were scattered to replicate the riverbed’s natural composition of sediment, gravel, and rocks transported by the current.

On the left side of the tank, a tree limb appears to dip into the river from the bank, with moss thriving in the moisture and gradually enveloping the wood. The right side slopes upward, creating an exposed zone where green algae coats several rocks, taking full advantage of unobstructed light – just as seen in nature.

Aquarium decoration

This 254-liter biotope is a recreation of a pool formed alongside one of the many rapids of the Escanaba River. The inspiration comes from years of fishing and exploring this beautiful waterway.

To build the foundation, I created a custom mix of dirt, clay, and gravel, forming a solid base. Additional substrate was used to sculpt the riverbed and rising banks. Large, smooth rocks are placed throughout, accurately representing those found in the Escanaba, polished over time by the rushing current. Gravel and small rounded stones were scattered to replicate the natural blend of sediment and debris carried downstream by the river.

On the left side of the tank, a tree branch appears to dip into the water from the riverbank. Moss thrives in the moisture, slowly engulfing the wood. On the right side, the layout rises to form a safe, elevated area where vegetation can grow outside the main current. In this case, mats of green algae have spread across several rocks, unobstructed by flow and fully exposed to light from above.

Together, these elements create distinct zones, each with its own niche and microcosm – just as in nature.

Aquarium equipment

Filtration: Fluval 207 Performance Canister Filter
Lighting: Lominie LED Aquarium Light

Fish care

For this tank, both fish are typically fed the same food. Red worms are provided every other day, along with daily feedings of dry fish meal. All fish are monitored during feeding, and none have begun to show signs of aggression.

Fish list:

  • Ambloplites rupestris (Centrarchidae)
  • Perca fluviatilis (Percidae)
Plant care

Plant care for this tank is fairly simple. The lights follow a schedule of 16 hours on and 8 hours off. Algae is trimmed if it becomes out of control or relocated if it shows signs of insufficient light.

Green algae:

  • Derbesia marina (Derbesiaceae)

 

Water care

Water changes began at 20% every other week and are now done monthly. The green hair algae aids in filtration. All water used has been purified.
