wasp Posted July 8, 2005 Report Share Posted July 8, 2005 I had some by accident around 5 ish years ago when I had a cold water tank. After a storm I collected some sponges and other stuff from the rocky area below Cheltenham beach. After it was established in the tank, a number of hydroids became apparent. The ones I had were somewhat similar in appearance to an aptaisia, but nowhere near as resilient. I suspect they were non photosynthetic although not sure. They would consume food if I fed them although it was difficult as they were so slow to grab it. Quote Link to comment Share on other sites More sharing options...
Chikan Posted July 13, 2005 Report Share Posted July 13, 2005 The only way I have ever successfully got rid of hydroids in my cold water tanks is too alter the salinity. If you have inverts in the tank this will be too risky. I removed the inverts I had like anemonies and sponges and dropped the salinity right down to about .015 for a couple of days. Fish will tolerate this change because they will be able to adjust to maintain homeostatis and osmosregulation. It worked a treat and then put back the inverts, this might not be practical to remove the inverts especially if you dont have anywhere to put them. Unfortunely the other option is a lot of hard work in cleaning and maintainence. Might be a help or not. Quote Link to comment Share on other sites More sharing options...

wasp Posted July 13, 2005 Report Share Posted July 13, 2005 Why get rid of them? I thought they were pretty cool. I never had enough to be a pest. Quote Link to comment Share on other sites More sharing options...
Brianemone Posted July 13, 2005 Author Report Share Posted July 13, 2005 apparently they have quite a nasty sting and mine are spreading quite a bit as well so nothing will grow/encrust where they are (my zoos) Quote Link to comment Share on other sites More sharing options...
wasp Posted July 14, 2005 Report Share Posted July 14, 2005 If they are a problem, I wonder if Joes Juice would get rid of them? Quote Link to comment Share on other sites More sharing options...
