As some of you may know if you read the rant and/or happy threads, the goldfish is finally going in a pond! Yay! Which means I'll get his tank, a 23 gallon. Now, that's no problem, I know precisely what I want to do in there. But I'll still have the 16 gallon in my room. It will have Odysseus, my male, 6 ember tetras and 6 panda cories.
Everything in the 16 gallon currently will be moved to the 23 gallon, plants, substrate, everything. This leaves me no idea what to do in the 16. I've attached a picture of what it used to look like. I changed the plant species in there since, but it's the shape I want you guys to see, not the interior. It is such an odd shape and I don't know what I can do with it.
My only thing is, I want it to be natural. Rocks, driftwood, plants, substrate, whatever, as long as it is natural. If you can provide links to products or to beautiful aquascapes you think could be adapted for my tank, please let me know. :) Thanks to anyone who can help!
