They are all dendrobates tinctorious: 2 citronellas, 2 powder blues, 1 Patricia. The temperature was 82 but turned of lamp it's now 76, hhumidity is 70%. Not sure how old they are but they range from about 1/2 inch to 1.5 inches. I think they are adults or sub adults. The pet shop said they were feeding them ff and sold me 2 cultures 1 well started and 1 just starting. I had calcium at home already so i dust ff both times I fed them, just got vvitamin and something call superpig to increase pigment (haven't used yet).
