Out of 4 platies, 2 are showing health symptoms that have me concerned. One has been sick for quite a while now...has gotten very thin, spends most of the time just bobbing at the top of the tank, with fins clamped. There is a slight s-curve of her body from side to side. She wants to eat, but has trouble keeping the food down. The other platy spends most of the time hiding in the tiniest, darkest spot she can find. She hasn't lost weight yet, and does appear to be trying to eat...comes out of hiding when the food floats by her. She seems to also have a bit of a s-curve. When she's not hiding in the dark, she's swimming erratically.
All four of my platies used to be in a 10g, along with about 10 fry (separated). I moved all the adults to a 20g, and left the fry in the 10g. The sickest platy was showing signs of illness just before I moved the adults over. The fry started dying one by one. The bigger ones were showing signs of curved spines before they died. They would have trouble swimming and rest on the gravel and decor often, and then would just disappear. Once all the fry died, I moved the sickest platy over to the 10g, and then moved the next sickest one. The other two platies seem to be okay at this point. The illness seemed to come on after having problems with stable temperature this summer. It went from being too hot, to too cool.
The tank parameters are 0NH3, 0NO2 and 10-15NO3, pH is between 7.8 - 8.1, KH and GH are high, and stable as always. I've tried raising the temp and adding salt, and lately have been using Melafix and Pimafix in the 10g (now my quarantine tank.)
So I'm trying to figure out what these fish are afflicted with. Could this be TB or am I way off the mark here? Could it be something else?
