Catalogue sizes: 2.5 cm, 3.5 cm, 4.0 cm. Use each offer code to identify the requested size; supplier prices and packing remain specific to that offer.

Specialist aquarium guidance gives 20-25 C and pH 6.5-8.0. Offer suitably sized dry foods with small live or frozen items. Feeding-time contact or nipping can occur; avoid very shy or slow companions and check that each fish obtains food.
