Aquanero;3957534; said:You say "for the past while he's been losing his appatite" how long is the past while? Does it have any corralation with the intro of the Jags? That has been your GT's tank for a year and now you upset the order of things. IMO 2 Jags and a GT in a 130 is alot. If there is a corralation between the intro of the Jags and the GT's odd behavior he is either stressed of trying to assert dominance. I would put him in his own tank and watch him if he's sick you probelbly just transmitted it to the Jags if he's not then the envoronment is no longer to hes liking. Is he still top dog or is there any fighting over turf going on?

He lived alone for a year then you put these new young jags in and his whole world is tuned upside down. Big change can cause big stress.
