Zixx777 Posted September 5, 2021 Share Posted September 5, 2021 (edited) I have a number of light pink plant-like things growing on my fresh water aquarium plants and glass. They really look like salt water coral- they have long feathery projections from the main body that move with the current. It is quite strange, as they just showed up and I have not added anything to the tank. Any help anyone can provide to identify what they are will be greatly appreciated! thanks!

Tihshho Posted September 5, 2021 Share Posted September 5, 2021 Less of a plant, more of a parasite Sorry to say, you've got hydra. 3 Link to comment Share on other sites More sharing options...
Guppysnail Posted September 5, 2021 Share Posted September 5, 2021 (edited) It is hydra but don’t fret….Stop feeding powdered foods and brine shrimp or yeast based shrimp foods for 2-3 weeks. They will cyst up. Vacuum your substrate then to reduce numbers. They are a harmless natural part of an aquarium. I have had these and the green ones for years. They are fascinating to watch eat. @Daniel posted an awesome video of them eating. They are in my shrimp and CPD tank as well and both species are very prolific. Aq coop does a great video on them and how harmless they are. Hope this helps edit. welcome to the forum!

Harmless to larger fish, to fry and baby shrimp not so much. 2 Link to comment Share on other sites More sharing options...

They occasionally get one or two of my shrimplettes but not enough to deter a population over abundance of shrimp I never seen them get a CPD fry (doesn’t mean they didn’t) but again not enough to be worried or lose sleep over. 2 Link to comment Share on other sites More sharing options...
Zixx777 Posted September 5, 2021 Author Share Posted September 5, 2021 Thanks! I have never had hydra before. I will stop the baby brine shrimp for a few weeks and see if that works. I have noted the CPD fry in the tank have recently been quite sparse - this may be my answer as to why. I may also get a couple of mollies and see if that helps as well. 1 Link to comment Share on other sites More sharing options...
Tihshho Posted September 5, 2021 Share Posted September 5, 2021 If you add mollies and have small fry in the tank, be aware they might go from sparse to gone. Link to comment Share on other sites More sharing options...

Scott P. Posted September 5, 2021 Share Posted September 5, 2021 I think that is the most Hydra I have ever seen in a tank. If it were me they would have to go. 1 Link to comment Share on other sites More sharing options...
