Hello everyone, to make a long story short- a few weeks ago one of my friends got me into fish keeping and I fell in love with it. Surprised I never realized how much I would like it earlier in my life. He gave me his old 10 gallon tank, and I went to PetCo and bought all the supplies that I needed.
I wish I would of bought a nicer filter, and thought that I might regret getting the cheap Aqueon 10 gallon filter, but honestly up to this point I haven't noticed any issues so I think it will be fine.
After treating the water and letting the aquarium run for 3 days I went to the store and bought 3 fish.
1 Silver Molly
1 Black Molly
1 Gold Twin Bar Platy
Here's where my question comes in. The silver molly and platy are really active, "hang out" real close to each other a lot, and are always eating! However I have yet to actually see the black molly eat (it's been 2.5 days). She just seems generally uninterested in food, and NEVER comes to the top to get it nor have I seen her even pick at food off the bottom. If she is eating, it's not when I'm around! She is also always in one or two spots, either hanging out in the bottom corner or like hiding right near the filter where it's dark. Occasionally she'll move around but it's very rare.
The fish does not seem to be sick at all, it swims fine and looks nice and healthy. Also, I know it's not water related because the other fish are doing fine and full of energy.
Anyone want to enlighten me on what could possibly be happening?
Also, here's a pic of my aquarium (before the fish went in it)
And here's my yellow platy
