Water Hydras
Jan 3rd, 2020 at 4:53pm
 
Recently I had a infestation in some of my aquariums with water Hydras.  I've never had any hydras before in many decades.  This happened, once I began using a new can of Brine Shrimp for hatching feed.

I am seeking any and all possible remedies which will work without disturbing a heavily planted aquarium.

Seeking advice,

I always kept a pair of blue gouramis around that I could move into a tank with hydra - they had it cleaned up in a couple of days, though I learned to keep them in the tank for about a week to keep any resting hydra from reinfecting - supposedly licorice and croaking gouramis also do a great job, and they don't get near as big as the blues - Flagfish also do a decent job, but they might also take out your plants

Thanks Kris,

Great suggestions, I'll look at the temperature of the gouramis and see if they're  compatible, that tank is around 71 dgF.

After looking at temperature, I decided to try pond snails because of the temperature in my killie tanks.  I'll report after a week or so.

Best wishes, Jim

Update,

After adding 4-5 small pond snails to my 55 gallon tank.  Almost all of the water Hydras present have been eliminated after three weeks.  To give a descriptive visual on how bad the infestation was: one side of the tank the forward glass looked like a silicone wave of hydras over 2/3 of the glass surface.  Literally there were multiple 1000's of hydras were present.  Now after looking at the same glass with a magnifier, I barely can see any hydras.

I want to thank everyone for viewing this post and making suggestions.

Hello Everyone,

My water hydras are undetectable now, I'm sure some linger somewhere in my 55 gallon planted tank, however, all hydras apparent on the glass are now gone.

I hope this helps,

Late to answer but I used Panacur C to clear up a hydra infestation I had in a shrimp tank.  It worked well but it will also potentially hurt any snails you might have in the tank.  If you notice them come back this could be a way to get rid of them long term. Pretty easy to use and can get it from a pet supply shop or amazon for cheap.

Justin,  this is heavily planted 55 gallon aquarium, I think Pancur C. would hurt the plants.

Thanks though!

I used it in a heavily planted tank with no troubles. But I'm glad the snails cleared it up for you.

I've always had good results clearing hydra with just a pinch of flubendazole powder/10 gallons. This dose did not seem to affect Malayan Trumpet snails nor harm any aquatic plants. If there is a single hydra present in a tank of fish being fed live brine shrimp nauplii you will soon be over run with hydras. (Also works great to treat velvet).

Hello,

Seachem Excel takes care of Hydra quite effectively.
