Yes, I believe it's a mold. I experienced the mold in 2 of my tanks while they were still new. I was told that it was called 'slime mold' and that it's caused from decaying food or decaying fish in the tank. Since you have pieces of food laying on the bottom with mold on them it sounds like you're overfeeding which might have caused it. That's what caused mine.

I'm not an expert, but I'll tell you how I got rid of mine.

I took out all the rocks and the 2 fake plants that were in the tank, rinsed all the mold off of them with tap water. Cleaned the filter out (unfortunately, I had to since it was full of slime) and while the rocks were out I vacuumed the gravel real well. Netted all suspended slime out of the water. I then treated with Maroxy and it was completely dead by the end of the treatment (5 days). After the treatment I did a final vacuuming to get any left over slime and netted out all remaining suspended slime from the water. Wiped out my filter one last time and put all the rocks back in the tank. The fish lived through it in both my experiences with it, and it hasn't come back in either tank since. I tried this same process without the Maroxy in my first experience with it and the mold didn't go away, it kept growing, so I do feel that the Maroxy was necessary. A guy who works at my LFS recommended it to me to kill the mold.

Hopefully this will help you in deciding how to rid your tank of it. I definitely recommend the Maroxy treatment if your real plants can handle it.

I've never kept real plants due to the fish I keep so I'm not sure how plants would handle it. I tried to do a search for it and couldn't find anything, and the bottle doesn't mention anything about plants. Maybe you could ask someone who knows a lot about plants or call a LFS you can trust to see if they know. Good luck with your tank, hopefully someone will come along who knows if this medication is safe for plants or not.
