Floating Tubifex Worms

Any suggestions on convincing thawed tubiflex worms not tofloat? Half of my ADFs worms floated instead of sitting on the bottom where they could find them. They don't loose their airbubbles very fast and are ending up stuck to my intake cover...I want to give the frogs their variety diet recommended by frogbreeder....just need a technique update for this one

 

Could u soak them in garlic juice as I reckon that it's heavier than water n might work maybe

 

Not sure if this will help, I've had decent luck with thawing worms in some water before putting them in the tank. Then I just use a turkey baster to get the food to the bottom.

 

Scoop up some tank water in a 1/4 cup measuring cup. Soak food in tank water or tank water mixed with Garlic Guard or Vita-Chem. Swish the cup into the tank and all the contents in the cup swirl down gloriously through the water column to the bottom of the tank.

 

So they aren't dumb hunters....just bad vision....if they surface for air in a floatingstorm of worms they will take their time going back to the bottom for a snack

 

Ended up sinking small jelly jar on its side on bottom of tank...large enough for all 3 frogs together....injecting thawed food with a needleless syringe into jar....worms still float but frogs can stand onnwall( now bottom) of jar and stand to reach all the worms
