My 10 year old and I would really like to get started owning dart frogs. I am new to Darts but not to Amphib's altogether. Have experience with breeding Asian Fire Bellies(I know they are much easier in comparision), and with red eyes tree frogs. I can't stand the thought of selecting some frail frog that will die on my 10 year old( I really like the look of Tinctorius, Lamasai, and some others but fear now killing one). He has dreamed of the day that he could own one for 4 years( I made him wait til he was responsible enough). We wish to have bold, colorful, prolifc, and HARDY type. Should I just stick with the Tricolors only? And if so, does anyone have any really nice ones for sale, and I understand that there are actually different kinds of Tricolors(what are they and could you point me to some pics and/or descriptions?) Thank you so much!

, just like that blue and yellow so much! Thank you to anyone who would offer expertise on the matter!
