Hi, I'm new to this forum & a relatively new frog owner. I've learned everything about keeping them & setting up the environment off the web, but I'm becoming concerned about their eating habits--I have 7 frogs total, and I've had them for about 5 months. However 2 of them are much more aggressive about eating and are becoming visibly larger than the others. Also, because there are 7 of them, it's hard for me to discern if everyone is getting their share when I put the crickets in. Should I separate the larger ones when I feed them, or separate them permanently?

Also, a couple of them are darker with less obvious spotting on their backs, they were somewhat darker when I got them, but now more so. I do put some calcium on the crickets & also frog vitamins about once a month, but I'm wondering if their coloring is something I should be concerned about.

Thanks
Heyjude
