I don't know if there's anything made especially for tree frogs, but Zoo med have a good calcium/D3 supplement. Repashy also makes a good calcium/d3, which is called Repashy SuperCal (I think...). However, I'm not saying that Nutrobal is bad. I'm just saying that it
might be less than optimal since it's designed for tortoises, which are omnivores.
Thanks , I'll check those out, I want the best for my little guy
Good! It can't be stressed enough how important it is to have a proper setup. When keeping red eyes, I would say that 90% (of course, it's just a number that really doesn't mean anything, since I can't actually prove anything scientifically) of the frogs well-being is having a good terrarium. If you want some inspiration, have a look at some of our members tanks. I would recommend Bshmerlie (Cheri) or DonLisk, for example.
