Plants to select

[David Chan]

Yesterday I bought two new plants for my tank. Both are ferns. Small one is tied to a drift wood and bigger one is tied to coconut shell. When i put the bigger one into my 2ft clear bottom tank, I notice that many light brown substance settled on the bottom. I vaccumed the bottom but after few hours, the bottom is filled with the substance.

Does anyone face the same situation? Is it harmful to the fishes?

The coconut outer shell has lots of fibres that would disintegrate, just a normal phenomena. It's not harmful to fish

Understood. I remove the plant from the coconut and tied onto my driftwood. Now my tank is bare bottom after removing the black sand so kind of unpleasant with the disintegration.
