Normal Or Just Odd?

[BaylorPerez]

SO i had just recently fed my danios some bloodworms. i had noticed one of them had started to take a "crap", and instead of the small little floating "crap", it was the bloodworm still intact, just instead of red it was tinted black, like the blood worm had broken through the danios belly(it is near the pectoral fin not actually on his belly). Is this normal? or just something i should keep an eye out if i feed the danios again.

Also, with feeding the bloodworms to my corys, are they supposed to stick out of their gills then go back inside their mouths, then back out their gills again?(i ask as i havent fed my corys bloodworms and when i saw the red thing sticking out it looked like one of their fins were coming off(Good thing i looked at it again to see it was about 1/4 of the bloodworm and not the fin coming off))

It's possible that the fish had a firm bowl movement that simply resembled the worm. 
 
As for the cory, they are "supposed" to do that, but they can. the gills are openings that go all the way through. 
 
It doesn't sound like you have anything to worry about.

the danio does have a extnded belly(like how one would be if preganant) but it hasnt laid eggs, or given birth(been getting mixed sayings on wether they are live bearing or egg layers). so i can assume this is constipation in my fish as my tetra has it as well

All danios are egg layers (and don't trust whatever person or website told you they were or might be livebearers in the future; that's completely wrong!).

It sounds like you might be overfeeding; fish will gorge on bloodworms (and they're not very nutritious either), so don't give them more than once or twice a week, and consider giving the fish a fast day, where you don't feed them at all, once a week, if you don't do this already.

i dont feed them usually on fridays, and i will start feeding the blood worms maybe every monday and thursday for my corys, and maybe just Wednesdays for my tetras and danios

I suggest no more than one feeding per week of bloodworms to any fish.  These are not really all that nutritious, not like prepared sinking foods, and they contain a lot of fat.  Most fish will greedily eat them, simply because such frozen foods are the closest thing to live, and this is also why difficult to feed fish can sometimes be started off with frozen foods to get them off live.
 
And I second fluttermoth to avoid overfeeding.  This takes some practice, but even if a normal fish only eats one little flake per day, it will be getting enough.
 
Corys sift food, and when it comes to larger solid food like worms, it takes them a while.  They do not have teeth like most fish, so they have to break the larger bits apart.  One reason for sand is so they can sift the sand through their gills in their search for tiny bits of food, a natural feeding strategy for these fish.
