Invisible Cory Fry!

[CBBP]

I was looking at my cory fry today and.. I noticed two little eyes swimming around!! the rest fo the cory was invisible besides alittle bit of the spine!! what is it!!

P.S. will different cories interbreed?

When the little ones are tiny fry they are see through. They gain color as they mature. It is one of the milestones of their growth. Fry of many fish if not all are like that. Maybe it was developed as a protection against predators. The fry that are invisable would be more liable to survive, grow up, and reproduce?

if they are totally "invisible" this means they have eaten their yolk sacs and therefor need some small foods such as microworms, they will soon aftten up with that stuff
