I’ve been feeding Omega One Super Color Flakes once a day. I haven’t seen any spitting food out, sunken belly, white string poop, or loss of appetite. I haven’t noticed any flashing. When one gets sick, they seem to get lethargic, sometimes hang out at the top, will bob around in the current. Maybe breathing just a little fast at first but it worsens. The loss of color is only right at the end.
I didn’t think about a chlorine spike that might have me underdosing the dechlorinator. I will have to test that. Although it may be too late to test it, since it should have naturally dechlorinated by now anyway. But if that was the culprit, it could have stressed them out even further and it is still taking its toll.
I left work last night with everybody looking happy and healthy. I came home this morning to a dead neon tetra, but everyone else looked ok. This afternoon, I had a guppy that was near the surface breathing a little fast and just kind of bobbing in the current in the corner of the tank. Now the guppy is sunk to the bottom, upside down, has lost color, and is breathing fast. Everyone else looks happy and healthy right now. I tried to get a pic/vid but because of where he is in the tank, you can’t really see him.
