looks like either a reidi or kuda, if he is eating well, that is good, most will say a 5 is too small, chance are he may grow to twice the size when fully grown if he is a kuda...he looks a touch thin, (not too bad), witha nano, water quality may slip from feeding, you may want to set up a feeding station (small cup or shell) to feed at...she will learn quickly...when she is done feeding suck up the remains so it doesnt go bad in the tank...ideally feed 3x/day (i feed mine 2x)

she is gorgeous tho...one other thought-she may need some company (not necessary and definitely not in a 5 but a thought for future)
