PROBLEM TO BE SOLVED: To provide a water tank for breeding plankton including jellyfish.SOLUTION: In a water tank for breeding plankton, a box-like water tank body 1 is partitioned into a water tank part 3 on the front side and a filtration part 4 on the rear side by a partition plate 2, and a water tank 5 having a generally circular cross section is provided in the water tank part 3. The water tank 5 is formed by inserting an attachable/detachable belt-like panel member 6 made of synthetic resin into the water tank part 3 and elastically deforming the panel member into an arc-like curved surface. The panel member 6 is elastically deformed into the arc-like curved surface along arc-like guide rails 7 provided inside the water tank body 1, an insertion front end part 6a is locked into a first locking part 8a provided inside the upper part of one side surface of the water tank body 1, and an insertion rear end part 6b is locked into a second locking part 8b provided near the upper part of the other side surface so that the cross section of the water tank 5 is formed into a generally circular shape. |
