Actually there are some fish who do not have hemoglobin (or even myoglobin.) The Antarctic ice-fish have a colorless blood without any hemoglobin molecules.
I've also heard that some fish have blood containing the copper-based molecule hemocyanin in place of hemoglobin, giving their blood a bluish color. (Hemocyanin is found in mollusks and some arthropods.) I haven't been able to find any supporting evidence for that claim, and I doubt that it's true.

All vertebrates are closely related, and all have the same type of blood, which uses haemoglobin to transport oxygen. When the blood has oxygen in it, it is red.
Animals with other colours of blood include arthropods and molluscs which use cyanoglobin, which is basically blue. None of these are vertebrates.

Ben H has it right. Some species of icefish in
the Antarctic have blood without hemoglobin.
In this cold water there is enough oxygen in
the water, and the metabolic rate of the fish is
so low that they can do without a special oxygen
carrying blood pigment. The amount of oxygen
dissolved in the blood is sufficient for them.
Amphibians and reptiles do have red blood,
contrary to one answer you received.

I don't believe that non -red blood exists in any of the vertebrates, since they all have hemoglobin containing blood cells.

Believe it or not, you don't have red blood, the red coloration comes from oxygen, blood is actually a purple color, when it is exposed to oxygen it turns red.

i've got faith that one and all MAMMALS have crimson blood because of the fact all of them hemoglobin. different sorts of creatures could have diverse colorings in accordance with what they use for oxygen uptake of their blood.
