ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to fish tanks and more particularly to an egg-laying tank for home aquarium with egg protection device.
BACKGROUND OF THE INVENTION
A conventional fish tank
1
is shown in
FIG. 1
comprising a housing
1
filled with water for raising fishes, a cover
11
applied thereon to securely close the housing
1
, and a plurality of pipes
13
on the side connected between a pump (not shown) and the wall of housing
1
so as to provide fresh air into the housing
1
. However, the previous design suffered from a disadvantage, i.e., fishes and laid eggs are not separated. As such, fishes may tend to eat eggs.
Another conventional egg-laying tank
20
for home aquarium is shown in
FIG. 2
comprising a housing
21
filled with water for raising fishes and at least one egg-laying containers
22
hung on the walls of housing
21
wherein each egg-laying container
22
has an inverted cone-shaped member
23
and a hole
24
at the small end. The egg laid by pipe may drop through the hole
24
by its own weight. With this, the purpose of separating laid eggs and fishes for preventing eggs from being eaten by fishes is achieved. But this is still unsatisfactory for the purpose for which the invention is concerned because feces and eggs both drop into the bottom of tank
20
to mix. As such, eggs may be contaminated.
SUMMARY OF THE INVENTION
It is thus an object of the present invention to provide an egg-laying tank for home aquarium with egg protection device so as to obviate the aforementioned problem of eggs and feces being mixed.
