I found this site and immediately thought it was unbelievable. A tank of 40 liters of gelatin only 2500? Love it. The more I researched, I learned that it is basically a biUbe / BiOrb.
I want more than anything else, is larger than the frosts, sell, receive. A 2 "Moons, you can click on the" office "kit, but also 6" moons, the Kit-go "Monaco". So ... I'm not an idiot. I recognize that these jellies will need to grow, and a 2 "Moon not be able to last a lifetime living in a small container, because the animals grow (DUH).
I'm so confused ... There is every kind of facilities / jellies have discovered that they) live on your desktop aquarium gelatin (BiOrb only in secret?

It makes no meaning.
Opinions, comments, suggestions? Jellyfish are never a good business for the layman at home?
