I just found 3 stuck to the glass, in an area of the tank my algae eaters have been ignoring... maybe they are sick of being stung? I have 2 red claws and 6 amano shrimp in with 7 cherry barbs and 3 otos.. one of the otos has been showing redness that I don't like, but the water shows no amonia...

how can I kill the hydra without hurting my crabs and shrimp?
 
Maybe the oto got stung badly, or got too close to a crab??

I would either A) drag them up the glass and torture them for hurting my fishys :devil: , or B) squish 'em with a net.
