Floating food cone
For the price you have and the use that can be given, it is worth it. If you remove the cone, it is good for you to put food floating and that the current does not take it.
Excellent for depositing frozen artemia. The discs peck the cone without the artemia sinking in the background
Certainly useful, if the fish have the idea to use it (only my scalars have understood, the others wait for the scalars to make crumbs);)
NUL much too expensive for the quality the cone and the ring are in one piece, the sucker does not hold the holes at the bottom of the cone too small.
This floating cone is not interesting at all. It is in one piece and the fish can not feed. The sucker does not hold.
