Wow, tank has been running in some way shape or form since the first week of September 2022. I have not added anything to this tank in quite a while (maybe 2 months), and it was just some macro algae I trimmed out of my display tank. I did take a small piece of rubble out of the back chamber and put it out front a few days ago, and low and behold, I have found my first Asterina starfish. This is the "Sin Bin" which is the name for my unwanted hitchhiker and macro algae grow out tank, so I will leave the starfish and see what happens.
