It's official!

Tomato is a Tom! He started calling last night! I'm so excited! He worries me a little though...Since I have 2 Whites Tree Frog and want to be sure they are each getting enough to eat, I place them in a 10 gal 3 times weekly, separately, and give them about 6 large crickets. Lettuce, the pig that she is, eats them all within minutes! But little Tomato doesn't seem to want to eat. I've had some issues trying to maintain the proper temp in their terrarium (small heating pad underneath and 150w Sunglo bulb during the day and I can still only get the temp around 75 F!) and yesterday I noticed a small red discoloration on his nose (not enough room?? 21g high, sorry I don't know exact dimensions and I can't find a tape measure). Am I just being a paranoid mom? Should I leave him be? I need a little reassurance if possible I do put about 15 crickets in the actual terrarium weekly, but I know they're really good at hiding!
