Patrick M. Bodega Aquatics Posted August 21, 2020 Share Posted August 21, 2020 A while ago, I began to notice this octopus looking thing stuck to my aquarium glass and decor. Does anyone know what this is? It has not seemed to make any difference to any of my aquariums. Is it a threat to my fish? I appreciate any response!

RovingGinger Posted August 21, 2020 Share Posted August 21, 2020 That is a hydra. I had them develop in one of my tanks too and was worried as they have a reputation for potentially eating fry. General consensus was they are not that worrisome, but kind of fascinating little signs of over feeding. Many fish eat them. I put some plants and rocks with hydra on them in the tank with my blood parrot and uh, well, that worked. 1 Link to comment Share on other sites More sharing options...
