I asked a question before and i said he was just sitting on the bottom and barely eating, a lot of you had asked if the water was cycled and yes it has been and has been heated, and i didn't add all 12 other fish at once, i did it gradually, and he was fine up until about 2 days ago, now he doesn't do anything, but he doesn't seem sick at all, also the pet store lady said the tetras that i had put in there with him would be fine, and if anything they would be the ones getting sick and acting weird, but it's just my goldfish that are acting weird, also put in chemicals that take out the bad stuff in water, and i have a great filter that produces a lot of oxygen, like i said before he was fine 2 days ago and now him and the other 2 goldfish just sit at the bottom. although the other 2 small ones swim around and eat still but they seem to follow my big and main goldfish. hmmmm not sure what it could be, and i don't think he's home sick, maybe just a little scared. not sure, any help?
