My black molly is not eating and swimming at the surface
So I've noted that my black Molly has not been eating for the last few days. Also, it seems to be spending more time at the surface. I have a ten gallon tank with a dalmatian molly and a black molly. I have a filter and do my regular partial water change every week (I did a water change yesterday as well - about 60%).

The black molly is pretty active otherwise and the dalmatian molly lives on as if it's life as usual. What could possibly be going wrong?

Another behavioral observation - the black molly swims up to the filter and does a little twitchy jig. It does that only on top of the filter. It could be just a little quirk but because it's not eating, I'm a little paranoid.

Any help/insights would be appreciated. Thank you.

Welcome to TFK first of all :-)

Can you provide your water parameters such as Ammonia, Nitrite, Nitrate, pH and water hardness? These will help us get a better idea of any potential issues in your tank.

when i hade my ten gallon and mollys i hade the same problem. i was told to get a bigger tank and to have 3 or 4 mollys together 1 male to 3 or 4 female along with live plants
so i got a 75 gallon now and my fish are all happy and eatting and also having babys now:)
maybe a 60% water change is a little to much at one time. try doing a 30% twice a week and see how you fish like it. i cant say to much as im new to fish keeping so i hope this help you out

when scaratching against tank decor can be a sign of whitespot which is common in mollys especially black ones. But also mollys do require salt in their water to keep them happy
