<P>PROBLEM TO BE SOLVED: To enable easy observing of the tortoises, etc. float on the water surface or climb onto the island from a bay by forming a wide closed water zone in a floating island body in an aquarium apparatus with a floating island for rearing aquatic animals such as tortoises which can climb onto the island and preventing such inconvenience that the grown tortoises, etc. are caught in a peripheral wall of the closed water zone and can not escape. <P>SOLUTION: The aquarium apparatus includes: the floating island body 1 onto which the tortoises, etc. can climb; a guide bar B to be fitted to the floating island body 1 in such a way as slidable in the vertical direction to guide the lifting of the floating island body 1; and a support means S for supporting the guide bar B to an aquarium A. One side surface of the floating island body 1 is formed as a flat vertical surface 1v approximated and opposed to one sidewall As of the aquarium A, and a notched part 1a opened in the vertical direction on the vertical surface 1v is disposed in the floating island body 1. A bay C in which the tortoises, etc. can float is formed by the notched part 1a. The inner peripheral surface of the notched part 1a is a slope 1si gradually descending toward the center of the bay C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
