Hmm, well, I removed some of the big rocks. There are no more rock caves. The bichirs display themselves more. I added a reedfish which swims a lot and is cool. I'm growing out some congo tetras which I'm hoping will get big enough that they won't get eaten. I have another, bigger, mopani wood soaking.
I'm thinking I'll avoid adding more large rock, and go for additional driftwood instead.
I need to find low light plants that get tall and would reach the top of my tank. There's only 64w of t8 fluorescent above it, approximately 1 watt/gallon. I'd prefer they match an african biotope but really I don't care that much. Suggestions?
