FishShrink Posted February 3, 2018 Share Posted February 3, 2018 These guys started showing up on the glass over the last week. Very small. Circular white center and multiple little strings/legs/tentacles sticking out. Anyone have any idea what they are? Link to comment Share on other sites More sharing options...
jolt Posted February 3, 2018 Share Posted February 3, 2018 Picture is small but I suspect that's a hydroid jellyfish. You can google them, they typically show up in newer tanks but I think they go away on their own Link to comment Share on other sites More sharing options...
Timfish Posted February 3, 2018 Share Posted February 3, 2018 Do they stay in one place or move around? This is the smallest brittle star I've videoed but they can be much smaller, it should give you an idea of how one looks when it's moving. If they pull in their tenticles when touched and don't move they're more likely hydroids. Link to comment Share on other sites More sharing options...
FishShrink Posted February 3, 2018 Author Share Posted February 3, 2018 Ok after looking closer I believe they are hydroids. Thanks for the help. We shall see how long it takes for them to phase out. Link to comment Share on other sites More sharing options...
