Yesterday afternoon I found my molly lying on the bottom of the tank, seemingly unresponsive. The moment I added some food, however, it shot up to the surface to feed and proceeded to act normally.
This morning, though, it didn't come up to feed. It moves erraticly and can barely get off the ground. It mainly just lies there and moves its mouth a lot.
I did a 20% water change last Sunday and changed the filters. It's a 55-gallon tank. He went into hiding after the previous water change but seemed fine within a day or two; nothing like this.
The platies and tetras in the aquarium all seem fine. Are mollies more sensitive?
Ammonia checks out OK, and I'll test the pH later today after I get a test kit. What else should I be doing?
