A device for feeding fish, especially pet fish, according to which a floating body for floating on the water in an aquarium carries tubular means which are inclined or arranged vertically upwardly from the floating body and are adapted to slideably receive and guide fish food bodies arranged one on top of the other. The lower end of the tubular means is partially open to permit fish access to the respective lowermost body of fish food in the tubular means while preventing a dropping-out of the fish food bodies from the tubular means. The invention also concerns a fish food body which may be ballshaped, may have a spherical head and flat bottom or a conical head and flat bottom or any other shape so as to assure when the fish food bodies are arranged one on top of the other, substantial contact point only of the lower fish food body with the next higher fish food body.
Food dispensing apparatus minimizes the likelihood that food particles dispensed into an aquarium will contaminate the water filtration system or will stick to the sides of the aquarium. The food dispensing system suspends a hollow food dispensing member in water in the aquarium such that the food dispensing member guides food to the bottom of the aquarium free from being transported by prevailing currents in the aquarium.
A semi-submersible fish feeder (1) for use in fish farms and aquariums which provides a feeding chamber (3) that floats below the surface of water and thereby enables edible materials such as food or medicine to be more controllably and evenly distributed to fish. A buoyancy aid (2) and ballast chamber (7) allow the depth of the feeding chamber within the water to be controlled. The feeding chamber is typically a volume of edible material enclosed by a net (10) through which fish can eat.
The automatic poison dispenser consists of a tubular element (5) intended for being mounted vertically at a wall (2), a pole or the like and containing stacked solid poison rods (13). At the lower part of the tubular element there are means (8) allowing an end portion (13') of the lowest poison rod (13) to be exposed for destructive animals at a certain distance from a floor (3). Screening means (9) prevent dogs, cats, etc. from getting access to the exposed end portion (13') of the poison rod. A poison preparation in the form of solid rods (13) contain poison but for an upper end portion (13"). To advantage the rods contain a mixture of poisoned so-called dry bait (typically about 2/3) and a stabilizing material or holder, preferably paraffin (typically about 1/3).
