Algae growing on the glass. Cause: Too much light or too many nutrients. Fix: Move to slightly lower light. Scrape algae off with a long brush (leave residue inside—it will break down).

However, proponents argue that for creatures like the Opae ula, the jar is not a prison, but a protected haven. In the wild, these shrimp live in anchialine pools—landlocked bodies of water with subterranean connections to the ocean. These pools often evaporate or become hypersaline. The shrimp are evolved to withstand stagnation that would kill a goldfish in minutes.

By following this guide, you will create a self-regulating ecosystem that can last for decades.
