With most varieties of viviparous (live- bearing) fishes it is desirable to promptly separate the mother and other fish from the young in order that they will not be eaten. One simple method is to take a glass funnel about six inches across the top, file a nick where funnel joins stem, break off tube and place a. Fig. 216.

One simple method is to take a glass funnel about six inches across the top, file a nick where funnel joins stem, break off tube and place a. Fig. 216. Funnel Trap for Live-bearing Fishes The obstruction in neck of funnel represents a piece of bent wire, and is, therefore open on either side. small piece of U-shaped wire in the opening, so that the wire divides the hole in half. The funnel is then placed in a cylindrical jar or other aquarium of a size that will suspend it by the edge, bring the water as high as possible in funnel, place female fish in funnel and cover over with screen, so she cannot leap out. The small wire previously men- tioned will prevent the mother fish from becoming jammed in the outlet, but will allow the young to pass through and collect in the lower portion of jar. Another very simple and effective arrangement is shown in Figure 217 being merely two pieces of glass laid in an aquarium at a sloping angle and set into two blocks so cut as to leave a slight space between the glasses at the bottom of the V. This opening should be just large enough for the young fish to pass through. The plan has the advantage of giving the female plenty of space. In fact several females could be kept in such a "maternity ward" at one time. Unless feeding on daphnia, a small butter dish or similar object should be placed across the bottom of glasses to catch the falling food until the.
