Hydra, not a disease, but I didn't know where else to post this

I have been feeding a small amount of microworms once daily in my 10 gallon Dwarf Cory tank at work off and on in an attempt to get them to breed for a couple months now. I went on vacation from two weeks ago and left pre-measured flake food for a coworker to feed while I was gone. When I returned to work I noticed one of my adult shrimp was dead and there were small white palm tree looking growths on the glass of the tank. I did some research and determined that it was Hydra. They had to be young because none were over an eight of an inch, fortunately. I found the below You Tube video that suggested that Hydra could be treated by using canine dewormer. I followed her instructions to the letter and as she said, three days later there were no more hydra and no fish or shrimp fatalities. I did a water change yesterday. When I came it today there are at least four of the tiniest shrimp I have ever witnessed so it must not have had any terrible effects on them.

Jenn, sorry. I haven't been checking the forum lately. Saw this thread. Hydra often comes in on plants or introduced during the feeding of some live foods and such. I liked the video and would like to try that chemical route next time I get Hydra!

Hydra are scary, I noticed one in my shrimp and guppy tank once and I panicked and grabbed my scale to weigh out some fenbendazole... when I went back over to the tank to put in the meds a guppy went right up and ate the hydra off the glass :ROFLMAO: haven't spotted one since then! What kind of pygmy cories do you have? I've got habrosus cories and I always find eggs after a (30%) cool water change. I don't feed anything special, to me their favorite food seems to be Hikari mini omnivore sinking wafers (the orange bag). Good luck!

I have corydoras pygmaeus, and they are spawning now. I think they weren't mature enough until the last month or two though. Now I see them doing their spawning dance once or twice a week. Hopefully they do it more I just miss it because I am working, lol!
