I have 2 leucs in a 20 gallon tank. The 1 Luec Ive had about a year . the other about 8 months. The 8 month old I raised from a really tiny juvi. My question is that the year old is about adult size but he/she doesnt look as big as the other. Is there a way to fatten up a dart frog ? I feed with fruit flies and occasional crickets. This is driving me nuts , over the last 2 years Ive lost 2 darts due to feeding . They start getting smaller and eventually die , due to lack of nutrition I guess . Thanks for any help !
