Just wanted to update pics and progress with this tank. I think we all go through the learning curve over time. I did feed spirulina powder but no longer feed at all. It does take waste from the opae to grow, feed, & produce algae. So maybe I fed the tank for too long but I'm ok with that. No filtration not even an air stone. The front glass has not not been cleaned off for over a month. Don't feel like cleaning it since there's a bunch of baby opae swimming around.
