I'm not flaming you. I actually complimented you on how well they look. I just didn't know how long they lived in that tank together in between breeding because it does look overcrowded and dirty on the bottom. They could live this way for weeks or for months, I don't know. I've seen a lot of bare-bottom tanks. I know how easily every speck of dirt, food, or feces shows up. Again, your fish look healthy and colorful.
