it is about 12" to 13" ... it is eating again... now. I tired pellets... but ate only one. So I just gave it supermeal worms.
I only had the aro for 2 weeks. I think it's 2 years old... maybe less??
Prior I did a quick water change 25%, checked all the water parameter.. making sure the nitrate and ammonia is near zero. Then the RTG was ready to eat.
So, I think water is a big part of the keeping a health aro...
