Very nice!
Im not sure if they stay small or not... Be interesting to see what size they are in 2-3 years.
I got mine at just under 7". she is now around 10" and more than doubled in thickness.... In under 5 months. She is now as thick as a 12-13" motoro.
I feed her twice a day, sometimes once, and she acts like she hasnt eaten in a month every time... She looks like she might explode after eating... I tryed feeding more, but she wont stop eating until there is no more food in the tank... even when her"feet" are unable to touch the bottom of the tank anymore(from an extremly full belly lifting them off the glass), she's still searching for more food.
Easy to train on any food you want to give though... she took to pellets as soon as she realized they were food. didnt have to starve or do anything special... just dropped them in.
Her colours and marking get better as shes grows as well....
wouldnt mind another one, but i think i'll try keeping them alone and not with other rays.
