Now this is what I call a Magical aquarium!

What Mr Choy means is the Glosso will overlap layer by layer over time, so you have to trim the upper layers off to prevent problems below.

You can't find such wood in Singapore right?

Sorry typo ,
I meant glosso will grow spreading horizontally & cover the substrate surface if the lights high enough...
Do they still grow vertically & add their layer even if the lights so high...?

Squee : wat do u mean with "wood on Singapore"...?

[|squee|]

They don't really grow vertically, they sort of "grow all over each other" if you get what I mean . It's like worms crawling all over each other.

I meant wood in Singapore , because I haven't seen this kind of wood in Singapore's LFSes.
