jaggedfire Posted January 16, 2013 Share Posted January 16, 2013 I have never actually seen one. Wanted to confirm. Height maxes at around .75" and 3/8" wide. Tentacles are pretty maxed here. Thanks Link to comment Share on other sites More sharing options...

ShawnM Posted January 16, 2013 Share Posted January 16, 2013 I second that Link to comment Share on other sites More sharing options...
+Mlaw Posted January 16, 2013 Share Posted January 16, 2013 I agree. For what that's worth. River City Aquatics has some in the live rock tank right now. They had more but have been getting rid of them. You can drop by and do a comparison if you want to be sure. Link to comment Share on other sites More sharing options...
jaggedfire Posted January 16, 2013 Author Share Posted January 16, 2013 I know most people kill these off. How invasive are they, really? I wish I had a small tank to experiment (and time)! Link to comment Share on other sites More sharing options...
Timfish Posted January 17, 2013 Share Posted January 17, 2013 Very invasive! Some animals can occasionally reach numbers that cause problems for some aquarists but not others. (I've seen tanks with just a few Aptasia that never seem to reproduce.) Majano's reproduce rapidly in every tank I've seen them in and can be difficult to irradicate once established.

+Mlaw Posted January 17, 2013 Share Posted January 17, 2013 I've always wondered why this is a problem? If you had them in a fish only tank so they weren't bothering corals would it be an issue? Do they sting the fish? Do something bad to water quality? Other than taking up real estate that you want to use for corals why are majanos so bad?

Peter Gott Posted January 26, 2013 Share Posted January 26, 2013 Mlaw, from my experience, there are three primary reasons people dislike them: A) They do sting everything that they touch. B) They reproduce like crazy, spreading faster than wildfire. That can even be a problem in FOWLR tanks, if you don't like the look of rocks where every inch is covered in majanos. And I do mean every inch. C) As mentioned, they are very difficult to eradicate...so of you decide that you don't like that look, by that point you don't really have any option but to take the live rock out and cook it, making it live rock no longer, and causing you to have to cycle the aquarium all over again if you reintroduce it. And most people eventually decide that in fact, they really don't like that look. Link to comment Share on other sites More sharing options...
Timfish Posted January 26, 2013 Share Posted January 26, 2013 You can also pick them off one by one which is what you have to do when they get into your colonies. Fortunately a LED light with some 400nm LEDs make them fluoresce green so they can be picked out from between polyps you want to save. Link to comment Share on other sites More sharing options...
Peter Gott Posted January 31, 2013 Share Posted January 31, 2013 I totally want them if you have any left btw. Link to comment Share on other sites More sharing options...
