Studying aquatic life under different conditions

The WISRD Aquatic Life Lab is working to simulate both freshwater and saltwater climates in order to observe and study the behavior of aquatic life.

September 19th, 2022: The Freshwater Tank arrived in the WISRD space. Megan and I (Max) constructed it and have since filled it with a floor of substrate. We laid seeds across this floor so that a carpet of plant life can cover the substrate which will help us maintain the nitrogen levels. Once that plant has grown, we will fill the tank with water (non-distilled water) and then we will add in the plants and animals! The main focus while we wait for plant growth is developing all of the filtration systems, both making sure we understand how they are used and having them ready to go for once the tank is set up. We also need to decide upon what will be added to the tank. Jadyn ( jadynb@wisrd.org ) has developed a list of life and items to add to the tank to support a relatively self enclosed ecosystem. Her research is as follows:

Tanks require lots of plants and some inanimate objects as well to help keep the tank clean. Rocks: (Black Mountain/normal Seiryu stones – provides great filtration, good hiding spots, doesn’t alter water ph). Plants: (Red Ludwigia, Hornwort, and Anacharis: good for oxygenizing tank ; Duckweed, Anubias Nana, Dwarf Sagittaria). Fish: (Bloodfin Tetras, Neon Tetras, or Black Neon Tetra, Harlquin Rasbora – all good in schools). Other Animals: (Amano Shrimp ; Siamese Algae Eater ; Mystery Snail – so pretty, good with all fish/good temperament). Summary/Assesment: (I think we should do some tetras, Siamese Algae Eater, Mystery Snail to start. all of these spices have good temperaments and get along well. tetras a beautiful and good at self regulation. there’s also so many plants we can get so any would work well. although we should get some flouters, some that are good for oxygenation, and some larger plant that can fill out the back. alone with this I think we should include limited hard scape such as the rocks I mentioned).

September 22nd, 2022: The Saltwater group currently has a temporary tank set up, with sand, salt water, rocks, and proper lighting. Megan suggested buying a second tank identical to the freshwater group’s, as their tank is better suited for the experiments we want to conduct and is more conducive to the urchin’s needs. The tank we initially set up might be used as a test tank, potentially being used to test alterations to the urchin’s ecosystem before we introduce them. The urchins arrive October 4th, so we are working on getting the tank and the necessary food set up before then.
