Hi! I wanted to introduce myself since I'm new. I have 4 opae ula shrimp that came in a biosphere, but I researched some information and decided that it was best to put them on a 17 liters tank. I'm from Spain and there isn't a lot of information here about this kind of shrimp. After some research, I found this blog and after reading, I made the decision to eliminate the sponge filter and a java plant. Now my opae ula are more lively so thank you for all the information! Here are some photos of my tank (before - with sponge filter an java plant- and after) I'm waiting for more decoration such as lava rocks to arrive. When my aquarium is settled I plan to purchase more opae ula.
