From my observations they show no preference or dislike for the colour black than they do for any other colour.
No,but guppies(livebearer types) can live with small sharks like dwarf shark e.g.
Fries (the term for baby guppies), are eaten by older guppies, but guppies are eaten by fish like tuna.
They are just guppies that are not quite as pretty as others.
People like guppies because they are small and cute
No. Guppies bear live young.
Adult guppies eat their own babies, and fish like tuna eat guppies.
Platys and black skirt tetras can live together. Harlequin rasboras, platys, and guppies are smaller than black skirt tetras and would do well together. However, the black skirts nip at fins, so if you have fancy tail guppies it is not recomended to put them in a smaller tank together.
Many male guppies have 'black spots' but if by "black spot" you mean "gravid spot" then no, a male guppy can not be 'gravid' because gravid is the equivalent of "pregnant" and male guppies can not get pregnant.
Yes and thay are freshwater fish. Most of the guppies at my pet store are orange or sometimes yellow, black and silver.
Guppies are fish. They do not have personalities like people do. They have evolved instincts and behaviour patterns.
id say guppies, they breed like rabbits
The plural of guppy is guppies. The plural possessive is guppies'.
