Hydra? Something else?

[WyoTrucker]

Hey nerms!

 

I've been cycling this 30gal for close to a month now. There's no fish in the tank, only a few ramshorn snails.

 

I'm noticing what looks to be very young hydra? I've never dealt with hydra but it's the closest thing I can find on Google that looks similar. Also detritus worms floating around in the tank. 

 

How'd I go about eliminating these? 

 

(Sorry for picture quality.. had to use a clip on macro lense on my phone 😅)

 

Thanks for looking! 

[AnimalNerd98]

I think I have seen this in my own tanks before. Do they dart around the tank if disturbed? They are probably copepods, little crustaceans that are a great source of food for fish. Once fish are added in, they should become rarer to find.

I think those are copepods.  You can get rid of them by adding fish.

[WyoTrucker]

I think y'all are right. They do dart around if disturbed. I don't know a ton about "invasive" beings in a tank, still new to the aquarium game. 

 

Plan on getting 10 Pea Puffers for this tank(hence the early addition of ramshorn snails lol)

 

Thanks a ton! 😁

Hey, I too also keep tarantulas! 😅

[AnimalNerd98]

No worries! I also got freaked out the first time I saw them. I have only seen hydra in tanks where I was heavily feeding baby brine shrimp. I actually found them fascinating. 
 

Whoo! I just have a solitary pea puffer but I hope to have a big tank with several pea puffers in the future! 
 

Heck yeah! I have a T. vagans, T. albopilosus, N. chromatus, B. hamorii, B. auratum, H. sp. colombia, and a P. metallica. I also have some tailless whip scorpions 🙂

Ummm, that's a lot of spiders! Verrry scary to a chicken like me but it shows you have the kind of love for nature/science that will keep fish alive 🙂

Type, as usual!

[AnotherHumanPerson]

This has probably been said, but copeopods 100%. Amazing fish food, I’d suggest taking some out and starting a colony.

That's me! I do everything in my control to make sure the husbandry is correct. 🤘

Now I know who to come to for tarantula questions 😂 

I recently went on vacation for a long stretch and had a friend watch over my slings. I had a Caribena versicolor sling die and I was heartbroken 💔 

I also purchased a group of Psytalla horrida juveniles several months ago, but only one made it. All the others had molting issues and died off. 

Luckily though, my fish have been breeding so I have been distracting myself with raising the fry rather than obsessing over my poor arthropods. 

[Luciferkrist]

Because of these showing up and some blooms of detritus worms, I have not been actively feeding my Chili rasbora/shrimp tank for about a month, and they could not be brighter red if I dyed them! Pretty sure they hitched in from a plant I put in, but my little tank residents LOVE them. 

Edited August 12, 2022 by Luciferkrist
grammar derp

[WyoTrucker]

Well... First it was copepods and detritus worms... Now there's definitely hydra in the tank.

 

I have 2 amano shrimp, 1 mystery snail and 4 adult ramshorns(hundreds of ramshorn snail-lets). I don't feed the tank but a pinch of krill flake every so often. 

 

So detritus worms are fine, copepods are fine. How'd I get rid of the hydra?

 

Man, I don't even have any fish in this tank yet. 🤣 

[Guppysnail]

Hydra are a natural part of an ecosystem. I keep 3 types in all my tanks incredibly fascinating. Once your tank settles in and matures with fish a good portion of them will cyst up. They are feeding on the microfauna (tiny detritus worms and copepods etc). Mother Nature does not like imbalances. So everything has a predator to keep numbers in check. Once you add your fish they will consume a good portion of the microfauna and starve out the hydra until you start feeding powdered food or live baby brine shrimp, microworms etc. I hatch Celestial Pearl Danio which are almost to tiny to see with the green hydra you have pictured. I have no issues with large successful spawn hatches. 
Enjoy the evolution of your tanks ecosystem and learn about they unexpected critters just like you would a fish. Learning their life and how to keep them healthy teaches how to keep population at an appropriate level for me. 
Anyway enough hydra fan girl 🤣 they are harmless so no worries.

Hey thanks a ton! Never dealt with this kinda stuff. Google and YouTube make hydra seem like the end of the world 😅

A lot of Google/YouTube stuff is made by newer aquarists showing things new to them. They make everything not purchased at the pet store epic disaster. Reality it’s all part of natural ecosystems. Mother Nature doesn’t make many mistakes. 🤗
