White cloud as hydra cure?

[Nav]

Has anyone had any success with white cloud minnows eating and eradicating hydra in a tank?

 

I know that sparkling gourami are probably the best at this, but I have a cold water tank which has a hydra issue.

Here is a video that might help. I keep 3 kinds of hydra in all 8 of my tanks because they are weird and wonderful (I know it’s not right for everyone) 

stop feeding fine powdered food, live/frozen BBS, daphnia and tiny organisms. After about two weeks they cyst up and a good vac removes many of them. Mine don’t come out for me to see unless I sustain feed powder high yeast(shrimp/fry) food live bbs consistently for 3-7 days. 
most folks do not like them but they are a part of any natural ecosystem. I have neo shrimp and hatch/raise teeny tiny CPDs with them present. I have no issues. They are not necessarily bad just possibly aesthetically displeasing to some. 
I hope the control method helps. I’m not trying to convince you to love hydra I promise. 😁

Yeh thats the weird thing,  that tank only has snails in it with no feeding of live foods only a piece of vegetable once in a while - hopefully they will die out on their own eventually 🙂

I have a very healthy population of hydra as well. I don’t think I’ve ever seen white clouds really pick at hydra but it’s worth a shot!

 

if you don’t feed heavy or at all then their presence means you likely have a pretty healthy micro invertebrate population. Hydra do eat FFA but it only makes up about 8% of their gut according to a few papers.

 

If you really don’t like them it appears others on this forum have used “no planaria”. It doesn’t seem to affect snails.

Yeh, they are an interesting organism! I will keep them around for a while and see how long they last in that tank. Eventually I might get some whiteclouds and see if they go for them or not

It reliably kills nerites, but doesn’t seem to affect ramshorns or bladder snails.  I haven’t treated a tank with mystery snails or other species of snails.

Oh, and I wasn’t treating hydra, I ignore those.  I was treating planaria.
