so after aquiring some new fish i noticed that some of my fish, new and old are acting weird, all the new ones were staying close to the surface, and staying pointed towards the bottom. one of the new ones died and one that i had for about 2 month's. today there is one new one staying behind the spray bar form my filter output. any ideas to what may be going on? i have tested my water and completed a water change. everything checks out, nothing changed really. im new to chiclids so please help. i bought 4 new fish, 1 is dead, 2 doing great now and 1 is hiding behind the spray bar like i mentioned.
