I think my tank finally cycled. The ammonia and nitrite have been sitting at 0 for 2 days without a water change and my nitrate is sitting at 5ppm. I did a 50% water change this morning because I didn't want to just stop the changes suddenly. I also added the river rocks that I've been wanting since I started planning this tank. My cories are all exploring and grazing and my betta is investigating every new rock. I'm so excited. It turned out exactly like I wanted it to. I even found a snail when I got the tank all put together!
Anyway, here's pictures:
Hehe, it's hard to tell what are cories and what are rocks. I think they like it that way.
All that's left is finding a new heater and florescent bulbs that fit in this hood.
