Fish and other animals are too large and create too much of a mess for a closed aquatic ecosystem. But small shrimp, snails, and copepods (small crustaceans) can do really well in them.
Hereof, what Animals Can you put in an EcoSphere?
Ghost Shrimp (Palaemonetes paludosus)
Ghost Shrimp, sometimes called Glass or Grass Shrimp, are the perfect addition to any beginner jarrarium. They are ultra-cheap at aquarium and pet stores, and very low-maintenance. They are omnivores, so they'll nibble on plants, algae, and detritus.
Beside above, how long do EcoSpheres last? The average life of an EcoSphere is between 2 and 3 years. The life expectancy of these shrimp is known to exceed 5 years, and the oldest EcoSpheres are now over 10 years old and still going strong.
Beside above, can you put a betta fish in an EcoSphere?
Ecospheres are absolutely not suitable for fish species of any type, it's more of a biology project than a actual aquarium. There is currently no “self sustaining” method of keeping aquarium fish in the hobby, unless you count a pond. Your better off purchasing a five or ten gallon with filter, heater, and live plants.
Can you keep a fish in a bottle?
Every species has different requirements for tank size, food and the chemical conditions of the environment it wants to live in. Due to size constrictions, only some species of small fish may be suitable for living in a bottle.
