I was under the impression that bloodworms sink...

I bought some "dried" bloodworms today, and they float.

is it the frozen bloodworms that sink ???

I haven't tried the freeze dried bloodworms but the frozen bloodworms sink.I do have freeze dried tubifex worms and they float

I use freeze died ones to and they float. I'm pretty sure they're supposed to float, all the ones I've ever used have floated. They eventually sink but the fish usually eat them before then.

mine float - freeze dried

question about "frozen" bloodworms:

they are sold in these little CUBE tablet pharmaceutical packaging....

I was wondering, are you supposed to give the ENTIRE cube and just drop it in ??
are you supposed to defrost the frozen cubes ??
the cube is quite large (it may take quite some time for bottom feeders to eat it all) - are you supposed to feed it everyday ?

also, when you are finished feeding the fish -
this might sound stupid...but are you supposed to put the bloodworms back in the freezer ??

Never re freeze anything, it can cause food poisoning.
Its best to thaw the bloodworms out before feeding. I put a cube in a dish and add a little water from the cold tap and they defrost in no time. If you have any left then place in the fridge. I only keep mine refrigerated for 12 hours and if they arent all eaten in that time then they go out.
Same for all frozen foods really. Ive found that brine shrimp go off really quickly as well.

The amount you give really depends on how many fish you have.I always defrost it first because I had one fish gobbled half of it.... I put the left over in the fridge and feed it dinnertime.I don't think you're suppose to put it back in the freezer.

Question: from 1 cube...how much bloodworms do you actually drop it the tank?
half a cube ??

Once defrosted i use a syringe to suck some up and slowly empty it in the tank. I only feed until it hits the gravel then stop.
I used to do this with the goldie as well and now that i keep tropicals i use one cube for the two tanks but the goldie maybe ate 1/4 of the cube in one sitting, so if you have two then half a cube is ample.
Suppose it varies from fish to fish and the size they are, but theres only so much they can take in one go.

LOL!! I did too with my Moor, he ate the whole thing in one gulp. Then his telescope eyes I SWEAR got bigger!!

I kept thinking of when I swallow ice cream too quick and my eyes hurt....... And i've defrosted them ever since...

Oh I can relate to that!This has made me so nervous I was yelling at my ryukin to spit it out!His mouth was soooo full he wasn't able to close it
