So I have a gold Gourami in my 75 gal
tank.. heís not completely new to the tank, Iíve had him at least a couple months. Iíve noticed the last couple days he occasionally has been hanging out at the bottom of the tank (generally in cover, behind the plants or under the rock structure). But he isnít inactive all day... itís only periodically he does this (where he didnít before the last few days). He still has no shortage of appetite, still always eats when I put food in. And he still swims right up to me when I walk up to the tank. Which made me think he may be stressed over something? Iíve checked the water parameters, and they arenít off. Any ideas? If itís stress, what kind of things can I do to help him out?
