I HATE HYDRA!!!!!!!

[Fishnut]

AAAAARG...they're in my CPD tank.  I have been wondering why the new fry are not surviving as well.  I found 3 hydra so far...I have a feeling it's the tip of the ice berg.  STUPID BLEEP BLEEP BLEEP HYDRA!!   

Research commencing...

if not invert in tank
anything with copper will get rid of them.

As zapisto said, copper, and as the daleks say, exterminate, as old B-films were prone to say, kill, kill, kill, they will kill all of your fry forever if you don't get a handle on them.

Show no mercy, give no quarter, o'er the ramparts and into the breach, destroy, destroy, destroy!

[Fishnut]

Copper it is!  I'll be making a trip to BA tomorrow.  Stupid little micro monsters.   

I read that if someone feeds copious amounts of brine shrimp, that they're bound to have lots of hydra.  How is that possible...BBS are salt water, clearly hydra are freshwater.  Is it because of the copious amounts?  The fish in the tank ONLY get fed BBS and bloodworms.

Sigh...

take care , after treatment with copper , no more invert in this tank for long time....
be aware of this

[Fishnut]

Oh!  For a long time?  Just as well.  I don't really want anything but CPD's in there anyways.

I've been researching this crap. It comes from BBS especially if overfeeding. So far I've read the 2 most suggested treatments: 1. 3% Hydrogen Peroxide but cannot find the consentration  2. Fluke Tabs at 1/2 strength

Dan, if you're able to, experiment with eradication and how the plants fare.  Since my infestation was mild, I was able to starve the hydra by not feeding any more brine shrimp to the fry.  They were happy eating flakes, and now I can't find any more hydra.

3% Hydrogen Peroxide but cannot find the consentration

You have to be very careful with H2O2, it can kill plants (vals, moos, hornwort ...) and fish (esp. scaleless one), and especially juveniles are very sensitive.

I dont know how good it works for hydra, i used it for algae. But i guess it will treat/harm every not too complex organism. A "normal" (quite safe) dose for 3% H2O2 is 2ml/100l. You can slowly increase it to max 20ml/100l. A dose of 200ml/100l is said to kill fish.

But using it with your juvis may still not be a good idea ...
