My platy tank has a shelf under it that has all my fish, shrimp foods, supplies, medication, ferts, etc, so every time I go near it, they hound me like they are starving, regardless if they just ate. They are little piggies. lol.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
Lol........yes, they could eat all day and all night. @ Sajacobs, the substrate is coarse textured PFS. It's great because it's heavy enough to gravel vac, but still looks like a fine sand. I picked up a 50lb bag of this stuff a couple of years ago for $10 or so. I got it at HD and the brand is quikrete.
