Hydra in the Shrimp Tank

Yeah, recently I've spotted a weird looking creature, at first glance thought it was plant material until it started moving. From certain research I also got the idea that it could be some sorta plant like organism as well, however it was a worm, a rather weird looking worm that both surprised and terrified me because I had guppies in there as well.

Anyhow, I killed it, but was wondering if it was harmful to the shrimps and if there's any methods that can be used to eliminate them if they ever do show up again, a simplier method then removing all the fish, etc, because we all know catching a bunch of small little fish in a planted aquarium isn't the funniest, if thats a word, thing to do. Not to mention by the way small tiny cherry shrimps.

Also, anyone know what chemicals, hopefully homefound chemicals that are safe to clean water plants for bacterial and parasitic creatures? Cause I think the hydras first came from the plants that I got and carelessly placed into my aquarium.

hydra is not a worm but a sort of freshwater "anemon", it is an invertebrate and like most of invertebrate hydra dont like copper and very high temp.
but the bad part is shrimp are also invertebrate and they dont like copper and very high temp either so .... :roll:
hydra is carnivor also and they can eat shrimplet

i will want to know what is the solution in your case .......

Yeah exactly thats what one website told me and then I got confused because another website told me that they were worms.

Red Ramshorns?

Some carnivorous snails are rumored to eat hydra. I had hydra in my tank a while back -- the population exploded when one of my shrimp (not an Amano, but something similar) released its larvae.

Since I've had several ramshorn in the tank (they have spots; I think they're 'European Red' or something like that), I haven't seen any hydra. Possible that it's a coincidence, but it might be worth a try. (Of course, now I have a snail problem...)

I rather be infested with snails then worms anydays, I don't know they just seem more managable, especially cause they're larger and they don't lay eggs inside creatures and make them explode with their babies, makes your skin crawl if you think about it, reminds me of a movie I watched....Aliens and Aliens vs Predator.

The solution I've seen is to remove all shrimp & fish, then raise the water temps up to 106 for an hour or so, then back down again. Most plants have no trouble with this, the the hydra get cooked.

I've not tried this my self. These suckers will eat baby shrimp.

If you do a search, you'll find lots of info on getting rid of hydra.

I did a combination of spot-treating with hydrogen peroxide and using red ramshorn snails.
