Should i defrost my frozen blood worms before feeding?

I would defrost the wholde cube as, in my experience, it is quite difficult to cut in half a fully frozen cube.

The fact that the cube is frozen will not alter the temperature of the water although most fish will not readily go for food that is frozen. In the case of goldfish, they will be greedy and can hurt themselves trying to gobble it down to quick.

In my opinion I have always defrosted the cube all the way before feeding and discarded any leftover. Do not refreeze whats left as it can become contaminated with bacteria which will harm your fish.

Live bloodworm are potential disease carriers and freeze dried bloodworm are not good for fancy goldfish as they can cause bloat.

However if you have tropical or marine fish then freeze dried bloodworm or prepacked 'delicia' which is bloodworm in jelly would be just as good as frozen.

Should i defrost my frozen blood worms before feeding?

I just bought frozen bloodworms. They come in frozen cubes.(12 cubes) Should i defrost the worms and feed my fishes or just pop the whole cube inside the tank? After defrosting a cube, can i put half in the tank and store the rest in the freezer again? Advise pls. thnks.

Frozen Bloodworms

I used to get a cup full of boiling water and cover it with Aluminium Foil and place a cube of frozen blood worms on it to thaw them out. Then all the fish have a chance of getting some. I found that some fish can be defensive and "guard" the frozen block so no others will get to it. Thaw one block at a time. If you find that 1 block is too much for them cut it in half and thaw only half of the block and return the remaining of the block to the freezer

What i do is, i have a little cup that i put the cube in and than i add some water from my fish tank to get it soft, that's if i am in a hurry. Other wise i let it thaw out by its self which really don't take long. I have never try to put it back in freezer I think i would just try and cut the cube in half if you don't want the hole cube.. Or next time you buy frozen bloodworm's get the kind that are not in cube than you can take out just what you want. GOOD LUCK

defrost first to be on the safe side thats what i do put frozen food in small container with some water from your fish tank and leave to defrost,cant go wrong ive been doing this since day one

Get a cup of water, either out of the tank or tap, it doesn't matter. Pop the cube into it and let it completely break up and thaw. Pour into tank a little at a time so the fish eat can eat them all. If the fish have had enough before the cube is done, toss the rest. Do not thaw and refreeze, bacteria will develop in the mix and infect your fish. It is not safe to feed fish refrozen bloodworm or brine shrimp. If you leave it out on the counter, even sealed up and it thaws you have to toss it all out, it is not safe for fish to consume.

I have had tropical and marine fish for over 4 years or so now. I just drop the blood worm in frozen and let is thaw out in the warm water of the tank. I don't like giving them fresh blood worm because I have found they don't all get eaten and live in the gravel. I did a major clean out of my tank once and while i was removing the gravel i felt something crawling on my arm. I looked down to see a blood worm. I had not fed them live blood worm for over 4 months.

I take some water out of the aquarium, place the cubes into it and then put this in the micro-wave oven for 15 to 20 seconds at a low setting. Then let this cool and slowly pour into tank. I would definetly not re freeze the left overs. Try and thaw out only what you think you will use.

Yes, defrost and rinse well any frozen food for your fish. Like human food, don't let it sit out too long or it will go bad.
