I was looking at my tetras today, and one looks skinny. Colour seems normal, it's eating, no red gills, the line is normal. It does seem to swim up and down a lot at angles, but I might just be paranoid. None of the others look strange in any way. The only real symptom is the skinniness.
Could it just be a female that reabsorbed eggs? One definitely looked gravid not long ago, and now I can't spot her. I just worry for my little fin-friends.
She seems to be gaining weight again. No odd looking poo. The tank is about a month old, nitrite, ammonia, and nitrate levels are good. There is some brown algae (diatoms) that has started up (I've been aggressively scrapping and scrubbing everything!). Posted via Mobile Device
