I have finally figured out fish selection for this tank. It took me a long time! I am going to leave the Danio albolineatus in there, and add a group of these... SeriouslyFish.com: Sewellia lineolata This is a great fish and I found a local source with a real good price. I am going to pick them up on Monday. So, this is not a Borneo-themed tank anymore; S. lineolata are from Vietnam. The D. albolineatus occur in Vietnam as well. This is exciting to finally have this figured out. I hope that I can get these loaches to acclimate well. If I can the rest of the setup all configured and cleaned up I will have lots of pictures on the way soon.
