I have a 90g with 4 comets. They are about 3 or 4 inches each. I noticed that they are acting kinda sluggish. One hides in back of the filter intake. The others are just "hanging in the same place". Their fins are not down, they are showing no sign of illness outside of this inactivity (they have been very active since I got them 6 months ago). I have not added any new fish to the tank.
The only thing that seems a little off is the pH of the tank. Nitrites are 0, Ammonia is 0 and Nitrates are 5ppm. The pH is 6. I was suprised, since my other tanks are at 7 or above. I must admit, that I don't check the pH regularly, so it may be that this is the norm for the tank. The substrate is pea gravel, and a single layer at that. The temp these days are 78 degrees.
I do regular water changes every 2 weeks (25 percent). I feed them Omega One goldfish flakes once a day. I just fed them, and not one of them ate.
Do they get like this, or do you think there's something wrong.
