Been a while. A year has passed and so many things has changed.
Somewhere arnd 5 months ago, the tank was conquered by BBA. The damn thing is everywhere - covered the rocks, the stem plants, even on the SAGs. Long story short, I had to ditch most of the plants. I took out all the rocks and let it dry overnight, then i manually rub off the dried BBA. Then rocks go back in. Many fish are already dead due to old age and sickness. Now there are just 2 green neons and 2 danios. sigh. not worthy of a pic anyways. so.. that's the update.
