They are similar to all other adhesive fish ova. They are usually attached to a plant or other fibre, tiny (less than .5mm), opaque, and will be seen only with a magnifying instrument. If they go white they have not been fertilised.
Yes, they will, although their is a five percent chance they will not and that their body has accepted the new change. When fish discolour or change colour it is a sign of stress, or being unhealthy. There is nothing to be worried about, for head and tail light tetra's it is very common for them to loose their brightness when sick, stressed or are not receiving enough light. You may have a heard the story that fish go white when kept in the dark, well for the head and tail light tetra this is true, but being put into it's natural environment it will go back to its natural colour. Although when sick it is best to have the aquarium light turned off. But not to have the fish in complete darkness, as they to need light to survive. There are certain chemicals and food that can be used to enhance the colour of your fish.
There isn't really a name but fish like Angler Fish, Viperfish, etc. have light on its head

Almost anything that is attracted to the light on its head.
is a species of angler fish.
Steelhead fish are also known as Rainbow trout; they typically eat just about anything they can get, but specifically like insects, fish eggs, and smaller fish.
I like neon tetras because they look really cool and different with their blue and red colors. They look like they are fake, though. It is really your choice, not mine. I like the fish named Guppy.
i think it is a type of goldfish?!?!?!?!?
