A shrimp bouncing slowly across the bottom or falling through the water column is a far better trigger than one just sitting there doing nothing, but don't be surprised if after getting a taste for prepared foods, the lionfish actively grows to recognise and take food whether its falling through the water column, or settled on the bottom (they really can be Hoovers on occasions).

一只到处游动的强壮的小虾比一只呆呆的在那里什么都不做的小虾更有吸引力，但如果驯饵成功后，狮子鱼一旦品尝到并习惯于人们提供的食物的味道时，无论食物是从水面落下还是静静的呆在缸底，都会非常积极地去吃。

In the first cultivation stage,as relatively high concentration of phosphorus,phosphorus from water column was removed to a certain extent by periphyton.The end of the incubation,as low concentration of phosphorus periphyton releases phosphorus to water column instead of removal phosphorus from water,this may closely relate to the alkaline phosphatase secreted by periphyton in water body.

从培养过程中水体磷的浓度变化来说，培养初期，水体中磷的浓度比较高，附着生物对其有一定的去除作用；培养后期，水柱中磷的浓度比较低，附着生物不但不去除水中的磷，而且还向水柱中释放磷，这可能与附着生物向水体分泌碱性磷酸酶密切相关。
