3 stripe damsel... behavior, systems 8/14/05 I have a 29 gallon tank that has one clown fish, two 3-stripe damsels  and 6 red leg hermit crabs --- and a young child.  I noticed last  night that one of the damsels was acting weird:  not swimming very much and  the white stripes appeared light gray. <Might be just night-time coloration... but this size, shaped system is too small for these three damsels (yes, the clown is one also)> I took him out and put him in a  quarantine tank.  I also discovered that the heater had been turned up to  83 degrees so I think this is what caused his problem (I have fixed the temp  problem and moved the control out of the child's reach).  The damsel perked  up almost immediately when I put him in the quarantine tank with water at 77  degrees.  When looking at him closely, I see that his fins are a little  ragged around the edges and there is a tiny bit of red right on the edge of his  tail fin. <Good observations... indications of stress, fighting perhaps>   He is to be swimming and eating okay.  My guess is that is  stress related from the temperature, but is it okay to put him back in the  tank?

Dascyllus How many Dascyllus would you put in a 30 gallon? <Depending on species none to one to possibly two... but this would likely be all you could place there fish-wise. Please see here re the genus: http://www.wetwebmedia.com/dascyllu.htm Is it okay to quarantine that n in a 10 gallon tank? <Just one. Bob Fenner> Thanks guys Pablo
Re: Dascyllus Thanks guys!!!!! More specifically Dascyllus trimaculatus or Dascyllus melanurus. <One, or two at most respectively. Bob Fenner>
