A pistol shrimp expanded a simple burrow into a deeper tunnel network visible against the glass, even cutting through roots with its claw. Another pistol shrimp used shells as functional barricades around its home, apparently trying to keep porcelain crabs out.

With the water clearer than it had been in a long time, the oysters made it possible to see more organisms and test the wave and tide system manually. The entry connects biological filtration to the next engineering check inside the marine habitat.

A day and a half after the oysters were added, the water looked much clearer as the oysters filtered plankton and algae from the water column. Their waste also became a new food source for shrimp, creating a visible new connection in the food web while the wave and tide system was still unfinished.

Five oysters donated through a viewer connection were added to the marine ecosystem and began affecting the algae within the first two hours. The test asked whether five oysters could provide the right amount of filtration for the system before they were permanently attached in place.

After an earlier sponge declined and had to be removed, oysters and a few small clams became the next candidates for controlling free-living plankton. The plan was cautious because too many filter feeders or a failed addition could quickly destabilize the ecosystem.

Work on the wave and tide system paused while OpenOcular was prepared for Maker Faire Orlando. The wave project still needed a stabilizing frame and linear actuator before the reservoir could be driven up and down automatically.

A duplicate update recorded the same pause in wave and tide system work while OpenOcular was prepared for Maker Faire Orlando. The remaining build steps were the stabilizing frame and linear actuator for automated reservoir movement.

A squareback marsh crab escaped from the system during an atmosphere refurbishment and was found crawling on Josue's leg. The incident exposed a temporary escape path while the atmosphere tanks were being rebuilt, and the crab was returned to the habitat.

miniBIOTA 1 was supporting a thriving population of Common Atlantic Marginella snails, including a confirmed second generation. The appearance of baby marginellas showed that the system could sustain detritus- and meat-eating snails through reproduction, not just survival.

The saltwater ecosystem had been running without pumps or filters because the plankton layer was feeding baby shrimps and other life in the water column. A sponge became a candidate filter predator that could reduce excess plankton while also creating habitat and passing energy through the food web.

The Marine Shore wave and tide system was manually tested before the support structure was built. Moving the reservoir produced visible turbulence, wave action, tide transfer across the beach, and nutrient circulation, confirming that the external mechanism could influence the closed ecosystem.

Condensation forming high on the atmosphere glass revealed the basic physics miniBIOTA would rely on for a closed water cycle. Warm humid air rose, cooled against the upper glass, and condensed there; once connected to the chiller, that same process could be used to drive rainfall without manually adding water.

The flat-backed millipede population remained strong after close to a month in the miniBIOTA 2 system, with no predators visibly reducing their numbers. The entry supports the idea that this detritivore group could persist long enough to help process dead plant matter.

A parasite was removed from a tiny shrimp using forceps and a dental scraper under the microscope. After the parasite was separated, the shrimp was returned to the ecosystem to continue living parasite-free.

The second wave and tide system update showed how water movement could be driven from outside the sealed ecosystem. The planned mechanism would move a chamber up and down to create waves, hold high tide, and lower the water again without disturbing the animals inside.

A possible shore crab pair was observed away from the fiddler crabs, with the female appearing to fan eggs. The species identity was still unresolved, but the egg-bearing female marked another reproductive event in the coastal system.

A pistol shrimp was observed defending its burrow by stacking shells near the entrance, apparently blocking a mud crab from sneaking into the space. The behavior turned a small pile of shells into a clear territorial engineering moment inside the coastal food web.

The early wave and tide concept used a moving reservoir that could raise and lower water to create both wave motion and tide effects. The design still needed refinement, but it established the basic direction: an external motorized mechanism that could move water rhythmically without placing powered equipment inside the habitat.

A visual update recorded the Marine Shore after 316 days of development. The entry preserves this stage of the coastal biome as a progress marker before later mechanical and ecological changes reshaped the system.

A new PETG rain system was installed on miniBIOTA 2, using glued channels, soaker hose, capped ends, and silicone tubing from the atmosphere tank. Once water ran through the cloud reservoirs and into the hoses, it fell back into the biome as rain.
