So my two frogs turned 1 yr old in June and I knew they were about done growing. I had always thought they were supposed to be bigger based on pictures I'd seen (their size was one of the things I was excited about when I decided to get some) but decided it must just look that way in pictures because there isn't really anything to compare them to. And then just recently I saw what they are supposed to look like in real life (saw their mother)...I was shocked. It wasn't just length, but overall mass. To give you some idea (and it's a bit rough since I was measuring her through the tank glass and she was getting upset because I wasn't feeding her) Ruby is about 4 inches head to foot, mostly stretched out, only like 2.5 inches head to butt. Her width in the belly area is about 1.5 inches. My male is slightly smaller. So now I want to know what happened, I feel like I have to be doing something wrong to have kept them so small.

It's the two of them in a 20 gallon long. They eat mainly reptomin with frozen bloodworms as a treat, this is how it's been since I got them. They ate every day when young, now they eat every other day. They are not underweight. I do water changes every other week and have a filter in the tank. The only "off" thing is that the water is a bit warmer than recommended, 80*F during the day, 77ish at night. The only other unique thing about our situation is they take a car trip 3-4 times a year because they come to college with me and I have to bring them home over long school breaks. They are active, eat like it's their job, and appear to be happy, but I just wonder why they stayed so small. If it's something I've done it obviously can't be good for them and I want to do something about it.
