Thanks guys.
Layout and plants not much change, but experiencing some algae problems. I think I've figure out the cause, but it'll take a few weeks to resolve.
The arowana is easier to mange. LOL. It developed a PLJ, but otherwise is ok. Cheeks started to "rust" a few months ago and the scales are just starting to rim with red. Some how the camera does not capture the red rims. I guess its a matter of lighting and angle.
Anyway, less words, more photos.
